Corrected entry: When Kilrain is lying wounded after the Battle of Little Round Top, the man on the far right helping him is breathing out vapor. I thought the Battle of Gettysburg was fought at the beginning of July, where they mention it's really hot.
Corrected entry: During the fight on Little Round Top Chamberlain's scabbard takes a bullet and ends up bent in such a way that the sword itself must have been bent as well, yet later in the battle when Chamberlain calls for the bayonet charge he draws an unbent sword from an unbent scabbard.
Corrected entry: In the opening, the spy is watching Union troops at dawn. He rides to Longstreet's headquarters and gets there in broad daylight. They then ride to Lee's headquarters and when they get there it is dawn again. Two sunrises in one day...
Corrected entry: In the Civil War cannon shells that exploded on impact were not used. The cannon shells at Gettysburg had timed fuses so that the shells would explode in the air casting shrapnel downward to cause casualties. If a shell landed before exploding, it would just bury itself in the ground and scatter dirt harmlessly when exploding. In the movie, the cannon shots all explode when hitting the ground, not in the air, and are obviously preset charges.By the way, this is why the Confederates overshot the Union forces at Gettysburg. Their main supplier had burned down just prior to the battle and they were forced to use fuses from another source. The Confederates did not yet realize that these fuses burned slower than their previous ones so the shell would travel further before exploding.
Corrected entry: As the Rebels are advancing towards the center of the battlefield, a white truck can be seen passing by in the background. (01:12:05)
Corrected entry: Colonel Vincent tells Colonel Chamberlain that the 20th Maine Inf. is the extreme left of the Union line, but in reality there was another regiment, the 19 Michigan, which was to their left. They were moved before the action began, but left behind about 60 skirmishers.
Corrected entry: Colonel Chamberlain didn't order the bayonet charge. It was his second in command, Spear. Chamberlain just followed along.
Corrected entry: In the first day's battle at Gettysburg, it shows John Budford's Union Cavalry defending their ground from the Confederate Army. Budford's boys use a stonewall for protection from enemy fire. The thing is that there was really no stonewall there in 1863 for Budford to hide behind.
Corrected entry: When General Longstreet is trying to talk General Lee into redeploying from Gettysburg, General Lee refuses saying that he has never left the enemy in possession of the field. But General Lee did retreat from the Battle of Antietam in September of 1862.
Corrected entry: When John Buford's cavalry are engaging Confederate infantry on the first day of battle, they are seen to be firing muzzle loading rifles, something which cavalry in 1863 would not be using. Rather, they would have had Sharps or Spencer breech loaders, the latter capable of firing eight shots before reloading. Later, when you see the cavalrymen firing from behind a fence, they now have breech loaders.
Corrected entry: There's a time when a battle is starting (either the third or fourth wave, I think) it shows groups of soldiers heading into battle. However, there is a time when a guy falls when they're charging even though no guns have been fired.
Corrected entry: In the scene where Tom and Lawrence Chamberlain are on Little Round Top and Lawrence is drinking coffee, way in the distance a vehicle is moving.
Corrected entry: Chamberlain's shoulder insignia change from Lt. Colonel (Silver Oak Leaves) to Full Colonel (Eagle) in the course of the three-day battle.
Corrected entry: In the sequence portraying the battle of Little Round Top, there is a miraculous lack of damage done to the vegetation. This was because that the filmmakers were given unprecedented permission to film the battle scenes at the actual battle site. This was only with the strict condition that no damage whatsoever was done to the landscape as Gettysburg is now a U.S National Park.
Corrected entry: During the battle of Little Round Top, the camera pans along the defensive line of 20th Maine soldiers firing from behind rocks. Irishman Kilrain begins to raise his musket only to have it go off too early. Evidently hoping that no one has noticed, he goes through the motions of aiming it even though the weapon is now empty.
Corrected entry: At the end of the movie, there is a scene where General Kemper is carried back to Confederate lines. He was actually captured by Union forces after Pickett's Charge and exchanged in early 1864.
