May 1st, 1863. The east bank of the Mississippi River, Bruinsburg, Mississippi. Ulysses S. Grant steps off a transport boat and onto dry ground. His boots hit Mississippi soil for the first time since this whole campaign started. Around him, thousands of Union soldiers are doing the same, pouring off boats, forming up on the bank, moving inland.
The crossing is complete. No Confederate resistance, no destroyed fleet, no army stranded on the wrong side of the river. The army is intact. It is on the same side of the Mississippi as Vicksburg. The road inland is open. Grant looks at the river behind him. Later in his memoirs, in his plain, matter-of-fact way, he will write that in that moment he felt a sense of relief scarcely ever equaled since.
That is what victory feels like before a single major battle is fought. But here is what you need to know about that moment on the riverbank. Two weeks earlier, Grant’s most trusted general, the man he considered his closest friend in the army, the man who understood him better than almost anyone alive, had written him a letter.
In that letter, William Tecumseh Sherman said the plan was too dangerous. He said the risks were too high. He said the fleet would not survive running Vicksburg’s guns. He said moving an army this deep into enemy territory without a proper supply line was contrary to every principle of sound military thinking.
And then he wrote the line that captures everything. I tremble for the result. He put it in writing. To his commanding general. This wasn’t a complaint whispered behind someone’s back. This wasn’t the kind of grumbling officers do in private and then forget. Sherman wrote a formal objection and sent it.
Grant read it. He considered it. He understood exactly where it came from. And then he ignored it. What happened next, and what it did to two men’s friendship, is the real story of Vicksburg. To understand how much courage it took for Grant to ignore Sherman, you have to understand the state of things in the winter of 1862 going into 1863.
Everything had been tried. Everything had failed. Vicksburg sat on a bluff above a bend in the Mississippi River, protected by geography in ways that made professional soldiers want to give up and go home. North of the city, the Yazoo Delta, a maze of swamps, bayous, and flooded forests blocked any direct approach from that direction.
The river itself was dominated by Confederate batteries on the bluffs that could tear apart any fleet trying to come at the city from the water. Lincoln called Vicksburg the key. He wasn’t being poetic. The city controlled the last major Confederate stretch of the Mississippi River. Take it, and the Confederacy is cut in two.
Lose it, and the war in the west stalls indefinitely. Everyone knew this. Grant knew this. The problem was knowing it, and actually figuring out how to do something about it. In December 1862, the first serious attempt ended in humiliation. Sherman led a force against Confederate positions at Chickasaw Bayou north of Vicksburg. He had nearly 30,000 men.
He attacked prepared Confederate defenses across swampy ground, and was thrown back with almost 2,000 casualties. The Confederates lost fewer than 200. Sherman retreated to his transports. The city was no closer to falling. Then came the long winter of canal projects. Grant and his engineers spent months trying to find a way around the problem.
They dug a canal across the neck of land opposite Vicksburg, hoping to reroute the river and bypass the batteries. The river didn’t cooperate. The canal project was abandoned. They tried the Lake Providence route. A complicated waterway through Louisiana that might allow boats to travel south without passing Vicksburg’s guns.
It didn’t work. They sent an expedition through Yazoo Pass, a channel once used for river traffic in the northern delta, long since blocked by a levee. Engineers blew the levee. Union gunboats pushed through. They got tangled in swamps and Confederate resistance and turned back. Steele’s Bayou another attempt, another failure.
Grant himself rode out to help Sherman, whose gunboats had become stuck in narrow channels with Confederates chopping trees down in front of and behind them. The boats barely escaped. By March of 1863, the Union Army of the Tennessee had been camped in Louisiana mud for months. The men were sick.
The press was furious. Northern newspapers were calling for Grant’s removal. Critics said he was incompetent or drunk or both. There were people in Washington whispering that this was not the right man for this job. Lincoln was not one of them. But Lincoln was running out of patience. The war was in its third year.
The public wanted results. Grant wrote to Halleck in early 1863. The letter was not long. It did not explain itself. It simply stated what he intended to do. I will have Vicksburg this month or fail in the attempt. He didn’t specify which month, but the clock was running. Before we move forward, I have a small request for you.

It motivates us, really. Thank you. Now, let’s get back to the action. The plan Grant formed by late March and early April of 1863 was, by the standards of conventional military thinking, almost indefensible. Here is what he proposed to do. March the Army of the Tennessee down the west bank of the Mississippi through swampy Louisiana terrain, through country that barely had passable roads, through the kind of ground that armies are not supposed to march through.
Then ask Admiral David Dixon Porter to run his fleet of gunboats and transports past Vicksburg’s river batteries at night. The same batteries that had stopped every previous attempt to move ships past the city. Then use those ships, assuming any of them survived, to ferry the army across the Mississippi to the east bank somewhere below Vicksburg.
And then, and this is the part that made experienced soldiers uneasy, move inland without a secure supply base. Cut the railroad lines that fed Vicksburg from the east. Defeat whatever Confederate forces came out to stop him. Come at Vicksburg from land, from the direction nobody expected. Take it in pieces, and each step sounds manageable.
Look at it all at once, and you see what military professionals saw in the spring of 1863. The fleet running the batteries might be destroyed. Once the ships were committed to running downriver past the city, there was no going back against the current. If the Confederate guns found them, Grant’s transportation capability disappeared, and his army was stranded in Louisiana.
Even if the fleet made it, the crossing itself could be a catastrophe. If Confederate Commander John Pemberton concentrated his forces at the crossing point, Grant’s men would be trying to land under fire. And once across, an army that has moved away from its supply base, cut its supply lines, and pushed into enemy territory with no clear retreat route, is an army that can be surrounded and destroyed.
This had happened before, more than once. There was a reason, doctrine said, you don’t do this. The safe choice was obvious. Pull the army back to Memphis, reorganize, launch a fresh campaign down the Mississippi Central Railroad line. The route Sherman had been trying to use in late 1862 before events complicated it.
Use proper supply lines, move methodically, take fewer chances. That was the professional soldier’s answer. That is what William Tecumseh Sherman recommended. William Tecumseh Sherman, in the spring of 1863, is 43 years old. He has seen enough of war to know how badly things can go. He was at Bull Run in 1861.
He commanded troops at Shiloh in 1862, that terrifying, chaotic two-day battle where Grant’s army nearly collapsed on the first day and only survived through reinforcements and the fighting qualities of the men on the ground. Sherman was wounded at Shiloh. He had two horses shot from under him. He knows what it looks like when a plan goes wrong and men die for it.
He also led the assault at Chickasaw Bayou just 4 months before Grant proposes this crossing. 2,000 Union casualties. The Confederate fortifications barely scratched. Sherman had watched men walk into prepared defenses and get cut apart, and he had carried that failure back to his transports. Sherman is not cautious by temperament.
He is impulsive. He is emotional. At various points in the war, he is too aggressive rather than not aggressive enough. But he is also a man trained at West Point, a man who has read military history and understands the principles behind it. And the principles say, “Don’t do this. Don’t run a fleet under batteries that can destroy them.
Don’t march an army across swampy Louisiana terrain to a crossing that may or may not hold. Don’t push an army into enemy territory and cut it off from its supply base.” His recommendation to Grant is clear. “Go back to Memphis. Use the river and the railroads. Approach Vicksburg from the north where conventional supply lines are possible.
Do it right, even if it takes longer.” And then he writes the line, “My own opinion is that this plan is too desperate. I tremble for the result.” Put yourself in the position of writing that sentence. You are writing to your commanding general, your friend, the man you trust more than any officer you’ve served with.
You are telling him formally in writing that you believe his plan will fail. You are placing your professional judgment directly against his. This is not disloyalty. It’s the opposite. A man who doesn’t respect you tells you what you want to hear. A man who respects you tells you the truth even when you don’t want to hear it.
Sherman believed Grant’s plan would destroy the Army of the Tennessee. He believed the boats would be sunk, or the crossing would be repulsed, or the army would be stranded in the Confederate interior without supply or retreat. He believed this with enough conviction that he was willing to commit it to paper.
And he was wrong. But he didn’t know that yet. Standing in the swamps of Louisiana in March and April 1863, watching Grant’s preparations and thinking through everything that could go wrong, Sherman trembled. Grant reads Sherman’s letter. He reads the concerns of other officers, too. James McPherson has doubts.
There are voices around Grant saying, “This is too dangerous. Go back to Memphis.” Grant does not go back to Memphis. His reasoning shows up in his memoirs and in letters from the time. It comes down to something that is not military doctrine at all. It is political and psychological reality. The North, he explains to Sherman directly, is already disheartened.
Think about what that means in the spring of 1863. The war is almost 2 years old. The Union has suffered catastrophic losses. Fredericksburg in December 1862, a slaughter. Chancellorsville is coming in May, another disaster. The casualty lists fill newspapers across the North. Families in Ohio and Indiana and Illinois have lost fathers, sons, brothers.
Politicians in Washington are asking whether this war can be won. Another retreat, pulling the Army of the Tennessee back to Memphis after months in Louisiana mud, would not just be a military setback. It would be an announcement that even Vicksburg was beyond reach. Exactly the kind of news that turns a demoralized public into a defeated one.
Grant cannot afford that. Lincoln cannot afford that. Grant also understands something about himself. A retreat to Memphis probably ends his career. He has already been nearly fired once after Shiloh. Halleck sidelined him for months in the summer of 1862. He has survived as commander of the Army of the Tennessee partly through Lincoln’s protection and partly through results.
If there are no results, the protection runs out. So, there is no going back. The plan goes forward. Night of April 16th, 1863. It is moonless. That is intentional. Porter chooses it because there is less light to make his ships visible to Confederate gunners on the bluffs. He has 12 vessels, gunboats and transports, loaded with supplies for the crossing.
The plan is to let the current carry them downriver past Vicksburg as quietly as possible, then use steam power once clear of the worst of the batteries. Grant is watching from a transport steamer near the opposite bank. Several of his officers are with him. So is his wife, Julia. So are their children.
Grant has arranged for his family, who have been visiting him in the field, to be on a transport to watch the run. Sit with that for a moment. Sherman believes this fleet might be destroyed by Confederate guns. Grant is certain enough it will survive that he brings his wife and children to watch. That detail tells you something about the difference between these two men at this particular moment.
The fleet begins moving around 10:00. For a short time, the passage is quiet. The current carries the lead ships south and the Confederates don’t immediately see them. Then they do. Confederate gunners open fire. Signal fires blaze along the riverbank to illuminate the targets. The night that was supposed to be dark fills with muzzle flashes and the sound of artillery.
The Mississippi at Vicksburg at 10:00 on an April night looks like something from a nightmare. Porter’s fleet fires back. The gunboats return fire while pushing downstream and out of range. The transports, slower and less armored, are the most vulnerable. One transport is destroyed.
One is badly damaged and driven back. Barges carrying supplies are lost. But the rest of the fleet makes it through. 12 vessels go in, 10 come out the other side below Vicksburg, below the batteries on the right side of the river. Grant is still standing on his transport with Julia and his children watching the fires and gun flashes on the bluffs above.
The plan is still on. Over the following 2 weeks, Grant’s army south down the Louisiana shore. The terrain is exactly as miserable as Sherman predicted. Louisiana in late April means mud and swamps and roads that barely deserve the name. 40,000 men move through it anyway. They are heading for Hard Times Landing on the Louisiana shore, directly across from Grand Gulf, Mississippi, where Grant intends to cross.
On April 29th, Porter’s gunboats bombard Grand Gulf’s Confederate batteries for 6 hours. It isn’t enough. The guns at Grand Gulf sit on high ground in ways that make them difficult to reach. After 6 hours, the batteries are still active. Grant stands on a gunboat watching the bombardment and makes his assessment.
A direct crossing at Grand Gulf will cost too many men. He needs a different crossing point. A local man tells him about a better option further south. Bruinsberg, Mississippi. A small landing below Grand Gulf, accessible by road with good ground on the east bank. Grant doesn’t hesitate.
He shifts the crossing south to Bruinsburg. On the night of April 30th into the early morning of May 1st, Porter’s fleet slips past Grand Gulf in darkness and moves south. McClernand’s 13th Corps begins loading onto the transports. While this is happening, Sherman is 60 miles north at Haines’ Bluff above Vicksburg conducting a demonstration, a loud, aggressive faint.
Firing guns, moving troops, calculated to keep Confederate attention away from the real crossing. He is helping execute the plan he told Grant not to attempt. May 1st, 1863, early morning. The Army of the Tennessee crosses the Mississippi at Bruinsburg. The landing is unopposed. No Confederate guns covering the crossing point.
No infantry waiting on the bank. The diversions, Sherman’s faint to the north, a cavalry raid by Benjamin Grierson deep through central Mississippi, have pulled Confederate attention in every direction except where Grant is actually crossing. 40,000 Union soldiers pour across the Mississippi River. No fleet destroyed.
No army stranded. No catastrophic repulse at the water’s edge. The river is behind them. Porter’s ships are intact, and the road to the Confederate interior is open. Grant steps onto the east bank. He writes later, “I was now in the enemy’s country with a large river and the stronghold of Vicksburg between me and my base of supplies.
But I was on dry ground on the same side of the river with the enemy. All the campaigns, labors, hardships, and exposures from the month of December previous to this time that had been made and endured, were for the accomplishment of this one object.” And then the line that cuts through all the doctrine and all the doubt, “I felt a degree of relief scarcely ever equaled since.
” That is not the language of a man who wasn’t sure. That is the language of a man who has been carrying the weight of a decision for 2 months and has just watched it work. Sherman’s fleet didn’t get destroyed. The crossing wasn’t repulsed. The army isn’t stranded. The plan that made Sherman tremble is now a bridgehead on the enemy shore.
What follows over the next 18 days is one of the most remarkable stretches of the Civil War and one of the least appreciated because it gets overshadowed by the long siege that comes after. Grant moves inland and he moves fast. May 1st, Battle of Port Gibson. Confederate forces try to stop Grant’s advance from Bruinsburg.
The Union forces outnumber them and push them back after a day of hard fighting. The Confederates retreat. Grant’s bridgehead is secure. May 12th, Battle of Raymond. A Confederate Brigade tries to slow McPherson east of Vicksburg. They are defeated and pushed back toward Jackson. May 14th, Battle of Jackson. Grant’s forces capture the Mississippi state capital.
Joseph Johnston, gathering forces in central Mississippi to threaten Grant’s rear, is driven out of the city. The major rail hub feeding Vicksburg is in Union hands. Now, Grant turns west. He has spent two weeks moving through the Confederate interior, winning engagement after engagement, keeping his army fed partly off the land, moving faster than Pemberton inside Vicksburg can process what’s happening.
Pemberton had been responding to each piece of news as it arrives. By the time he reacts, Grant is somewhere else. May 16th, Battle of Champion Hill. This is the decision point. Pemberton comes out of Vicksburg with around 20,000 men to meet Grant. The two armies collide on and around Champion Hill and the fighting is brutal.
Back and forth, charges and countercharges, a Confederate thrust that nearly cuts Grant’s army in two at one point. For several hours, it is genuinely uncertain. But Union forces hold. Then they push back. Then Pemberton’s line breaks. After Champion Hill, Pemberton is no longer a general with options. All that is left is to retreat behind Vicksburg’s walls and wait.
May 17th, Battle of Big Black River Bridge. Pemberton’s rear guard tries to hold the river crossing. Grant smashes through them in less than an hour. May 18th, Union forces reach the outskirts of Vicksburg. 18 days, five major battles, five victories. From the crossing at Bruinsburg to the siege lines around Vicksburg, 18 days.
Sherman was wrong about everything. The fleet survived the battery run. The crossing succeeded. The army didn’t starve in the Confederate interior. Rather than concentrating and destroying Grant, Confederate forces had been defeated one at a time. Port Gibson, Raymond, Jackson, Champion Hill, Big Black River.
Each before they could mass into something strong enough to stop him. Every specific fear that Sherman put into writing has been disproved by events. Grant had seen something that Sherman couldn’t see. And Sherman knows it. Not just at the end of the campaign, during it, while the battles are still happening. Watch what Sherman is doing during those 18 days. He’s not a spectator.
His core is actively engaged. He fights at Jackson. He marches hard. He executes. But somewhere between Port Gibson and Champion Hill, something changes in how he’s watching all of this. He had been right about doctrine. Every concern he put in that letter was professionally legitimate. The things he warned Grant about, fleet vulnerability, deep penetration without a supply base, the dangers of moving inland with your back to a river.
These were not invented fears. Military history was full of armies that destroyed themselves by doing exactly what Grant was doing. But Grant had done it anyway, and battle by battle, it was working. Sherman starts watching differently. Less as a subordinate executing orders, more as a student trying to understand what he’s seeing.
What he sees is this. Grant is not ignoring the risks Sherman identified. He has weighed them against a different kind of risk, the risk of not acting. The cost of retreating to Memphis, six more months in Louisiana mud, another round of failed canal projects. What that would do to the men, to the public, to Lincoln’s ability to keep prosecuting the war.
Sherman can see the battlefield risks clearly. He can calculate them and build plans around them. What he cannot see, not yet, is that inaction carries its own cost. A cost that accumulates slowly in newspaper headlines and desertion rates and political speeches, rather than all at once on a battlefield.
Grant can see both. That, Sherman will later conclude, is what makes him different. In his post-war writing, Sherman is unusually direct about this moment. He does not pretend he was right. He does not claim he secretly agreed with Grant and only objected for form’s sake. He says clearly that he was wrong.
He had written, “I tremble for the result.” The result was that the Army of the Tennessee crossed the Mississippi, won five battles in 18 days, and placed Vicksburg under siege from the landward side, exactly as Grant had planned. What Sherman realizes somewhere in those 18 days is that Grant sees the war differently than he does.
Not recklessly, not luckily. Differently. Able to hold two opposing risks in his head at once and choose the one the moment requires. That is a hard thing to admit. Sherman is not a man who lacks confidence. He has strong opinions. He holds them firmly. The idea that someone else’s judgment is simply better than yours, not in one small area, but in the essential skill that defines what you’re both doing.
That is a difficult conclusion to sit with. He sits with it. He writes the letters. He writes the memoirs. He says he was wrong and Grant was right. And then he says something more. After Vicksburg, he would follow Grant anywhere. Not because Grant outranked him. Not because he had to.
Because watching Grant take that army across the Mississippi into enemy territory without a supply base, winning battle after battle, arriving at the walls of Vicksburg with an intact army, watching all of that happen. Sherman developed the kind of trust that is almost impossible to manufacture and almost impossible to break.
He had seen what Grant was. There is a thing that happens sometimes between two people who have been through something together. Not a shared victory, a shared disagreement. The victories are easy. Shared victories make friendships feel simple and inevitable. Of course they’re close. They won together.
What is there to argue about? The disagreements are where you find out who someone actually is. Whether they tell you the truth. Whether they can be wrong and admit it. Whether their friendship can survive one person being right when the other was wrong. Without the wrong one spending the rest of the relationship resenting it.
And without the right one spending the rest of it reminding everyone. Grant and Sherman had already been through one version of this from the opposite direction. After Shiloh, after the press firestorm, after Halleck arrived and took operational command away and reduced Grant to a meaningless staff role, it was Sherman who talked Grant out of resigning.
Grant was ready to quit. He had been humiliated publicly. He was being blamed for being surprised at Shiloh, which he disputed but couldn’t fully counter. He was sidelined, irrelevant, staring at a position with no real function. Sherman went to him and told him to stay. He told Grant that the war was bigger than one bad newspaper season.
He told him that he himself had gone through public humiliation. In late 1861, Sherman had been reported in the press as nearly insane, sent home by his own superiors, finished. And that staying and fighting through it was the only choice that mattered. Grant stayed. This is the other side of the ledger.
Sherman had saved Grant’s career by knowing something Grant couldn’t see. That the career was worth saving. That the public humiliation would pass and the work would remain. Then, less than a year later, Grant saved the campaign against Vicksburg by knowing something Sherman couldn’t see. That the risk of the river crossing was smaller than the risk of retreat and that military doctrine is a starting point, not a ceiling.
Two men, two moments, each one seeing something the other couldn’t. Each one with the relationship solid enough to say the hard thing and then, when the hard thing turned out to be wrong, solid enough to admit it. This is not common. Look at the Civil War’s history of generals and you will find the army full of men who couldn’t do this.
Men who buried their mistakes and blamed subordinates. Men who never admitted error and spent their post-war years writing memoirs that relitigated every battle in their favor. Men who poisoned their relationships with other commanders through jealousy and credit stealing and score settling that lasted decades.
Grant didn’t lord the Vicksburg success over Sherman. There are no accounts of him reminding Sherman that he had ignored his advice. No letter saying, “Remember when you told me this would fail?” He filed no grudge. He held no victory lap over his friend’s objections. Sherman didn’t deflect or minimize his error. He wrote it down.
He said he was wrong. He said Grant could see things he couldn’t. He took the lesson and applied it. And the result of that is the partnership that carries the Western war to its end. What comes after Vicksburg for these two men is almost a direct consequence of the trust built during it. Vicksburg falls on July 4th, 1863, the same week as Gettysburg in the East.
The Confederacy loses its grip on the Mississippi. The country is cut in two. Grant is eventually given command of all Union armies in March 1864 when Lincoln finally finds the general he has been looking for since the war started. And when Grant goes east to handle Robert E.
Lee in Virginia, he leaves Sherman in command of the Western armies. Sherman takes Atlanta in September 1864, the capture that arguably saves Lincoln’s re-election and thus the war itself. Then he marches to the sea through Georgia, through the Carolinas, burning the infrastructure that feeds the Confederate war machine and breaking the will of a population that had believed it was invincible.
This is the same man who trembled for the result in the spring of 1863. The march to the sea works in part because Sherman has internalized what he had learned at Vicksburg. He watched Grant cut an army loose from its supply base and move it through enemy territory, living off the land, moving fast, keeping the enemy confused.
Sherman does this on a scale that dwarfs the Mississippi campaign. He could not have conceived it with enough confidence to execute it if he hadn’t watched Grant prove the concept in Mississippi. The teacher and the student. Except that both of them teach and both of them learn at different moments about different things and neither of them forgets what the other showed them.
Late in the war, after Atlanta, after the march to the sea, Sherman reflects on his commanding general, the man he had known since they were both obscure officers in peacetime before anyone outside the army had heard either of their names. What he says across letters and conversations from this period comes down to something simple.
He stood by Grant when the world called Grant crazy. Grant stood by his plan when Sherman called it too dangerous to attempt. That is the whole thing right there. Two men who had been publicly humiliated. Two men who had doubted themselves and doubted each other. Two men who had disagreed in writing about the most important military operation either of them had ever attempted and who came through it closer than before.
I tremble for the result. Sherman wrote that in the spring of 1863 looking at a plan he believed would destroy everything. The result was Port Gibson, Raymond, Jackson, Champion Hill, Big Black River Bridge, Vicksburg. The result was one of the most audacious campaigns in American military history. Conducted by a man who could not be talked out of his conviction that the risk was worth taking.
The result was Sherman himself watching it work, updating everything he thought he knew about what a general could be. And years later, the result is two old soldiers who remember a night in Louisiana when the fleet ran the batteries and everything could have gone wrong and didn’t.
And the friendship that held through disagreement and humiliation and war long enough for both of them to find out what they were capable of. The fleet ran the batteries. The army crossed the river. The city fell. And the general who said it couldn’t be done became the general who proved in Georgia and the Carolinas that it could be done on an even larger scale.
Because he had seen with his own eyes what it looks like when a man refuses to be stopped by reasonable fear.
