For the XI Corps, it was a sad reminder of their retreat at Chancellorsville in May. Under heavy pursuit by Hays and Avery, they clogged the streets of the town; no one in the corps had planned routes for this contingency. Hand-to-hand fighting broke out in various places. Parts of the corps conducted an organized fighting retreat, such as Coster's stand in the brickyard. The private citizens of Gettysburg panicked amidst the turmoil, and artillery shells bursting overhead and fleeing refugees added to the congestion. Some soldiers sought to avoid capture by hiding in basements and in fenced backyards. Gen. Alexander Schimmelfennig was one such person who climbed a fence and hid behind a woodpile in the kitchen garden of the Garlach family for the rest of the three-day battle. The only advantage that the XI Corps soldiers had was that they were familiar with the route to Cemetery Hill, having passed through that way in the morning; many in the I Corps, including senior officers, did not know where the cemetery was.
