I wouldn't even call it a breach unless you call a few Confederates crossing the wall a breach. Every Confederate that crossed the wall was killed.
In the
Battle of Gettysburg, Armistead's brigade arrived the evening of July 2, 1863. Armistead was mortally wounded the next day while leading his brigade towards the center of the Union line in
Pickett's Charge. Armistead led his brigade from the front, waving his hat from the tip of his saber, and reached the stone wall at the "Angle", which served as the charge's objective. The brigade got farther in the charge than any other, an event sometimes known as the
High Water Mark of the Confederacy, but it was quickly overwhelmed by a Union counterattack. Armistead was shot three times just after crossing the wall. Union Captain
Henry H. Bingham received Armistead's personal effects and carried the news to Union Major General
Winfield Scott Hancock, who was Armistead's friend from before the war.
