Gettysburg Map Morning July 1, 1863
The credible evidence shows that General Lee planned his army’s encounter with the enemy at Gettysburg many months before beginning the movement from Virginia. This is evident from the testimony offered by credible eye-witnesses: A.L. Long, his military secretary, and Isaac Trimble, and from the fact that Jed Hotchkiss drew for him road maps that included the mountain road
from Shippensburg to Arendtsville. The idea was a classic one: by sending Ewell’s corps toward the Susquehanna River, with Early’s division marching east as far as York, his brigades and cavalry reaching Wrightsville and Hanover, Lee induced the Union army to string itself out to the northeast, along the Mason-Dixon line, its corps reaching as far as Manchester to cover the threat that Ewell’s
corps, followed by Lee’s main body, would move on Baltimore or Washington. When, after the war, Longstreet talked about the “agreed upon” plan being to “force” the enemy to attack the Rebel army, instead of the army attacking the enemy, he was referring to the political pressure that would be brought to bear on the Lincoln government to move on the offensive against Lee. The conflict
between the pressure to move on the offensive and the necessity to wait for Lee’s movement toward the Mason-Dixon Line to develop, caused Meade, with the backing of Halleck, to stand on the defensive for three days. Only in the middle of the night of June 30/July 1, when the word came from Harrisburg that the rebel forces on the Susquehanna were falling back, did Meade decide to move his
left wing toward Gettysburg and confront Lee’s main body that he had known for almost forty-eight hours was camped in the twenty-two mile corridor through the South Mountain, between Chambersburg and Cashtown.
In calculating the time table that would bring the two armies in contact at Gettysburg, General Lee had expected that the enemy’s advance would reach Gettysburg on June 30th. This is proved by Jubal Early’s post-war testimony in his letter to H.B. McClellan and in his writings in the Southern Historical Society Papers and in his posthumous autobiography. When he
met with Ewell at Chambersburg, on June 25, it was understood between the two of them, Early states, that they would march toward each other on June 29: Ewell from the vicinity of Carlisle toward Early, and Early from York toward Ewell, the junction point designated at that time to be Churchtown, a point on the northern extreme of the South Mountain range. But neither Ewell nor Early marched
toward each other on the 29th. What had changed the time table?
General Lee controlled the record of his instructions to his corps commanders through his control of the Gettysburg Letterbook. He did not allow his staff to make any record of his actual movements orders, from the time he crossed the
Potomac, on June 25, to sometime on or after July 1, when he allowed Charles Marshall to copy into the book his instructions to Imboden to bring his cavalry to Chambersburg and relieve Pickett’s division from its role as the army’s train guard. At this time, his aide, Walter Taylor, had taken the place of Robert Chilton as the assistant adjutant general of the army, a position Taylor held,
not as a member of Lee’s personal staff, but as a member of General Samuel Cooper’s, the Adjutant General’s, office in Richmond. As such, just as Chilton did during the Antietam campaign, Taylor was responsible for maintaining his own letterbook in which his duty as AAG required him to copy all movement orders Lee issued. Chilton’s letterbook exists in the National Archives today because it was
part of the records sent by Cooper in a wagon train to Goldsboro, N.C., when Petersburg fell. Where is Taylor’s letterbook?
Without any credible written record of what orders Lee actually issued to his corps commanders between June 25 and July 2, we are left to rely upon the testimony offered by a number of witnesses, first in their battle reports, and, later, in the post war years, their public writings. Longstreet, Ewell, Early, and Charles Marshall prominently fall into this category. But, when
compared to what the elements of Lee’s army actually did, their stories conflict in important ways. For some reason, Ewell and Early did not march toward each other on June 29 as they had planned on June 25. No record exists as to why this is so, except that the enemy was not moving toward Gettysburg on that day as Lee had expected. Despite the political pressure to move forward, the enemy was
known, by the 28th, to be concentrated instead around Frederick. To induce the enemy to move toward him, Lee must have caused orders to be sent to Ewell and Early to fall back toward the South Mountain. Those orders reached Early on the 29th and both he and Ewell began marching toward Heidlersburg on June 30.
While they were marching, Lee had an infantry brigade, with at least a squadron of cavalry, advanced to Fairfield within observation distance of Emmitsburg. John Reynolds, in command of Meade’s left wing (1st and 11th Corps, to be supplemented by the 3rd Corps at Taneytown) was aware of this force and this force certainly had to be aware of
him. When Reynolds moved the 1st corps northward several miles, camping at Moritz Tavern, Lee could anticipate that the following day, Meade receiving the news of the rebel fall back from the Susquehanna, that Meade would then be “forced” to take the offensive against him. This is what Lee wanted, what he had been waiting for patiently to happen, because Meade’s movement almost
certainly would mean his army would arrive at Gettysburg in pieces, and Lee was reasonably sure he could overwhelm the advance and throw it back on Meade’s main body.
Meade, for his part, thought the same thing. This is why he delayed and delayed, with Halleck’s concurrence, in taking the offensive. Until he was certain his right flank was not in danger of being attacked and turned by the enemy appearing from the direction of York and Hanover, he stand on the defensive at the Mason-Dixon Line. Even when he was sure the danger had
passed, he still was unwilling to assume the offensive against Lee. His experience with Lee stretched back to the battles on the Chickahominy, included Lee’s attacks at Gaines Mills, Malvern Hill, Second Manassas, Sharpsburg, and Chancellorsville. He knew from experience that Lee was extremely aggressive and it made him certain that, indeed, Lee would be coming toward him and that his best
countermove was to meet Lee in a defensive position. Still, the pressure to move built up in him and, at 4:00 a.m. on July 1, John Reynolds received his order to move the 1st Corps forward, supported by the 11th Corps. The evidence clearly shows, in doing this, Meade expected Reynolds to do no more than advance to the point his front made contact with Lee’s, and then fall
back fighting, slowing Lee’s advance as well as he could, and take position in the center of Meade’s defensive line at Taneytown. By slowing down Lee’s anticipated advance, Reynolds would be giving Meade time to bring into line behind Pipe Creek the 2nd, 12th, 5th, and 6th corps, on the right of Taneytown, and the 11th and 3rd
corps on the left of it.
John F. Reynolds, however, had a different plan. Like Meade, Reynolds was from Pennsylvania and anxious to protect his state from Lee’s marauding. Like Meade, he had moved up the ranks through the experiences gained in handling first a brigade, then a division, then a corps, through the battles the Army of the Potomac fought with Lee, from the Chickahominy to the Potomac.
Like Meade, Reynolds was ambitious and his ego was chaffing to win recognition as a fighting general. Indeed, it is claimed that after the disaster at Fredericksburg, Lincoln offered army command to him before he offered it to Hooker. Reynolds is said to have turned the offer down because Lincoln exercised too much control over how the army would be allowed to move.
However Lee’s and Meade’s actions set the stage, the battle of Gettysburg happened because John Reynolds decided to make it happen. When Reynolds rode ahead of the 1st Corps to Gettysburg he knew from reports received from Buford that A.P. Hill’s corps was massed just back of Cashtown, that the by-roads were infested with prowling cavalry patrols, and that Ewell
was marching with Rodes from Carlisle, and Early from York, toward Heidlersburg. This could only mean one thing: If he were to engage the enemy the likelihood was great he would eventually be fighting on two fronts—Hill’s forces coming at him from the west and Ewell’s from the north. Under such circumstance, Meade would expect him to fall back, but he had no intention of doing so.
Reynolds rode into the town of Gettysburg. He saw high ground offered by Cemetery Hill and the long ridge connecting it to the Round tops and immediately recognized it provided a defensive position as strong as the position Meade had selected at Pipe Creek. Instantly, he decided his objective was to hold the enemy west of the town, long enough for Meade to bring the army
forward. At this time two of Henry Heth’s rebel brigades—Archer’s and Davis’s—were rapidly driving back Buford’s skirmishers from Herr Ridge and moving against his main line at McPherson’s Ridge.
Reaching Buford’s position about 10:00 a.m., Reynolds saw the rest of Heth’s division in line of column coming forward on the Cashtown Road and immediately put his mount to the gallop and went back across the fields toward the Emmitsburg Road. As he rode, he calculated time, distance, numbers, thinking he could organize a battle line that could match Heth’s, hold the ground
Buford was on and bring up the 11th and 3rd Corps. Reaching the road in the vicinity of the Cordori Farm, he came upon Cutler’s brigade leading the advance of the 1st Corps. Here he sent a message to Meade that he was going to engage the enemy and another to Howard to hurry the 11th Corps forward. Then, with the 147th N.Y. Regiment, he
recrossed the fields to McPherson’s Ridge and directed the regiment where to break down from column into line.
As the 147th NY was moving across the fields, Buford’s troopers were falling back from McPherson’s Ridge, with Archer’s brigade advancing from south of the Cashtown Pike and Davis’s brigade advancing north of it.
Putting the 147th NY into line on the north side of the pike, engaging Davis, Reynolds galloped back toward the Emmitsburg Road and took charge of the Iron Brigade, directing its regiments toward the stand of trees that covered the middle ground of McPherson’s Ridge on the south side of the pike. Archer’s brigade was rushing up the western slope of the ridge as
Reynolds got the Iron Brigade in line and sent it into the woods. “Forward men, for God’s sake drive those fellows out of the woods,” he is claimed to have shouted, as the 2nd Wisconsin Regiment charged the front of the 14th Tennessee. Both regiments let loose with a rifle volley at a distance of fifty yards, staggering the fronts of both. Reynolds followed the
2nd Wisconsin into the woods. Here, as the fighting became almost hand to hand, Reynolds reined his stallion around, looking off to the southeast, straining to catch sight of the flags of the following Iron Brigade regiments, when a bullet slammed into his brain, killing him instantly. Reynolds had been on the ground for little more than two hours when he was killed, but in that time
he had given General Lee the opportunity he had planned so long for: One Union corps was now engaged with his front and had no choice but to fight, disengagement impossible without mad flight, making it certain that other Union corps would be drawn piecemeal into the coalescing battle.
Here, as Cutler’s brigade fell back from McPherson’s Ridge to Seminary Ridge, Abner Doubleday, acting commander of the 1st Corps, assumed command of the battlefield. On the south side of the pike, the Iron Brigade stopped Archer’s brigade cold, pushing it back to Willoughby Run, then back to Herr Ridge where it met the advance of Heth’s reserve brigade and withdrew
to McPherson’s Ridge. In the process of this, the rebel front on both sides of the pike withdrew to Herr Ridge and the firing dropped off to a lull. Without a credible record of Lee’s orders, no one can know with certainty why the lull developed, since it is obvious if he wanted to, Lee could easily have crushed the 1st Corps before any support could have arrived. The most
reasonable explanation for the lull is that Lee ordered Heth to reduce the intensity of the struggle, to encourage the 1st Corps’ support to come up. Lee had Rodes and Early poised on the north of the battlefield, and expected their force, cooperating with Hill’s, could destroy two Union corps.
About 11:00 a.m., Howard arrived at the head of the 11th Corps and, as senior officer on the field, took command of the battlefield from Doubleday. Leaving Doubleday to handle the Union front facing Hill, Howard rode onto Cemetery Hill, directing two of his divisions to take position north of it and face Ewell’s force that had appeared on Doubleday’s flank, the
deployment occurring about 2:00 p.m. At this time the closest supports behind Howard, were Slocum’s 12th Corps, then approaching Two Taverns about five miles from Gettysburg on the Westminster Road, and Sickles 3rd Corps, about 14 miles away reaching he vicinity of Emmitsburg.
Howard’s two divisions—Schurz’s and Barlow’s—faced Rodes. Rodes attacked at about 2:00 p.m., as Heth’s fresh brigades—Pettigrew’s and Brockenbough’s—renewed pressure against Doubleday’s front. The battle now raged on two fronts, with some initial Union success in resisting the onslaught pushed by O’Neal’s and Iverson’s brigades of Rodes’s division, but now Early’s force
appeared and, with a line of three brigades, Gordon’s, Avery’s, and Hays’s. Buford sent here a message to Pleasonton: “We need help now.” Between Doubleday’s front and Howard’s, there was a gap which Rodes and Early forced themselves into as Heth attacked again, while Rodes pushed forward Daniels, Ramseur’s, and Doles’s brigades. Behind Heth came Lane’s, Scales, and Perrin’s brigades from
Pender’s division. The weight of these brigades crumbled first Howard’s lines and then Doubleday, his flank exposed, ordered retreat.
Now the Union defensive position collapsed. . . first the men trickling away, then a stampede and a flood. . . Here Barlow was killed. Doubleday had taken huge losses: Wadsworth’s division had lost over half its strength, Rowley’s division the same. Most of the field officers were dead or wounded. Robinson’s division, the last of the 1st Corps had lost 1,600 men
out of 2,500. The Iron Brigade lost two thirds of its men. Heth’s division likewise was decimated by the four hours of fight.
The time had come for Lee to administer the coup de grace, to swarm after the fleeing Union troops, pursuing them into the town, through the streets, around the edges, and up and over Cemetery Hill driving them down the roads toward the Mason-Dixon Line. It didn’t happen. Despite all his planning, the long preparation, the incredible physical effort of an army of 60,000
soldiers, with thousands of horses and hundreds of wagons, walking a hundred miles to reach the battlefield, it didn’t happen. There certainly was time enough: It was only about 3:30 p.m. when the Union front collapsed and the men, chased by Heth’s and some of Pender’s men, with Rodes’s and Early’s, rushed pell mell for Cemetery Hill. Howard was there with a reserve division, but that division,
another one of the luckless German ones that failed at Second Manassas and Chancellorsville, hardly could be expected to have stood up against a fresh rebel division throwing itself upon it.
The Cashtown Gap
According to Jacob Hoke, writing his The Great Invasion after the war, on the Monday night, June 29, “sometime in the after part of the night, say 2:00 a.m., a continuous stream of wagons coming back from the direction of Carlisle, and turning east at the Public Square of Chambersburg, drove onto the Gettysburg pike”: a low rumbling sound, grinding wheels—this was part
of Ewell’s trains, a twenty-five mile long wagon train passing into the twenty-two mile long corridor between Chambersburg and Cashtown, where already there was crammed two divisions of Longstreet’s corps camped at Greenwood, and R.H. Anderson’s division behind Pender’s at the eastern mouth of the Cashtown gap, plus Hill’s trains somewhere, perhaps in a mountain cove, or side road. So the night
of the 29th, Lee, camped at Messersmith’s Woods on the eastern suburb of Chambersburg, had to be aware Ewell’s trains were heading into the corridor and what their presence meant to his ability to get his divisions out onto the rolling plain between the eastern face of the South Mountain and Gettysburg.
At this time, the night of the 29th, Lee must also have known that Ewell’s third division, Edward Johnson’s, was camped about Shippensburg, perhaps his lead brigade camped that night close to Green Village, on the road leading to Fayetteville and the Cashtown road through the gap. Longstreet writes in his From Manassas to Appomattox that he and Lee camped
the night of the 30th at Greenwood and the next morning, July 1, rode together toward Cashtown. About noon, Longstreet writes, they encountered Johnson’s division appearing at Fayetteville and cutting into the Cashtown road, Johnson being accompanied by his own division train. At this point, he says, Lee ordered him to hold his divisions so that Johnson’s could pass first. This means
that Ewell’s corps trains must have passed through the gap on the 30th, reaching Ewell’s position at Heidlersburg either that night, while Johnson moved on the 30th toward Green Village, continuing his march the morning of July 1. With these facts in mind, certainly General Lee, as early as the night of the 29th, could have foreseen the bottleneck that would occur
at the mouth of the Cashtown gap on July 1, the day, given Rodes’s and Early’s movement toward Heidlersburg, he could expect the encounter battle with the enemy to commence.
Perhaps this development forced Lee to change his plans, to delay initiating a battle with the first of the Union corps to appear at Gettysburg, to delay long enough to get Johnson’s division out of the gap and connected to the rest of Ewell’s corps. Perhaps, but we cannot know because Lee did not record his orders. The “sketch” he allowed Charles Venable to write in the
Gettysburg Letterbook cannot be relied upon as evidence of his orders; given its text, and the identity of the writer, it is obvious Lee drafted the text after he knew the result of the first day’s encounter. The only reason the sketch exists in the letterbook seems plain to be Lee’s excuse for Ewell’s trains and Johnson’s division being out of place; i.e., Ewell was first ordered to march toward
Chambersburg which justified him ordering his trains south with Johnson’s division, while the second part of the text, explains Lee’s change of plan, brought on not by an intent to assume the offensive but by an intent to protect his communications.
Longstreet’s statement of timing seems clearly wrong since the evidence shows that Johnson’s division had reached the vicinity of Early’s position on the 1st at about 4:00 p.m. This means that the head of Johnson’s division must have reached the mouth of the Cashtown gap around noon on the 1st; since marching at a pace of three miles per hour,
would bring the head of the division to Early’s position about 4:00 p.m.
General Lee had a crucial decision to make here: Which division—Johnson’s or Anderson’s—should Lee order march out of the gap first? He had to think of the end point of the encounter battle—the anticipated pursuit of the broken Union force toward the Mason-Dixon Line. The prime tactical consideration for him had to be the issue of which direction did he want his pressure to
force the Union retreat toward: southeast toward Westminster, the enemy’s obvious base of supply, or south toward either Taneytown or Emmitsburg? If the former then Anderson’s division would be best to go out first, since it could pass through Pender and Heth and drive directly east against Cemetery Hill. If the latter, then Johnson’s division should go out first, to pass around to the north and
push the Union retreat south. Clearly, as Johnson must have been marching through Fayetteville early on the 1st (it’s 12 miles from there to Cashtown: a four to five hour march), Lee had time to move Anderson out of the gap to make room for Johnson to pass. But did Anderson have room to move out behind Pender? Indeed, since Anderson would have to move out before Johnson arrived at
noon, did Lee think it prudent to show the first arriving Union corps so much strength? If he did, would the enemy commander realize his force was too weak to make any kind of successful stand against him? And, thus, not engage west of the town, but wait on the Emmitsburg Road for Lee to advance and then slowly retreat toward Maryland where Meade’s defensive position was situated? Here it
seems plain Lee gambled. His prime motive was to draw the Union advance into contact with Heth, leaving Heth for a time unsupported as encouragement to the Union commander to solidify the engagement, allowing his forces to become fixed in a struggle not easily broken off without disaster. Then as a second Union corps appeared push out Pender and bring down Ewell. So he held Anderson behind the
gap and let Johnson come out first, after the battle was fully raging, gambling that the slight superiority in numbers he had achieved in the battle would be sufficient to press the pursuit, with the possibility that Johnson might arrive at his designated spot in time to reinforce it. When the moment of crisis came, it seems at least part of Johnson’s force had come close to where it should have
been, and but for the lack of Stonewall Jackson’s character it failed to rush forward to attack Cemetery Hill before dark. So in the end the game came down to Jackson’s absence from the field at Gettysburg.
