The division was commanded by Brigadier General Alexander Hays (USMA ’44), a Mexican War veteran who had worked as an engineer on bridge and railroad projects in Pennsylvania. Hays had commanded the Third Brigade of the division until three days before the battle, when Major General Wiliam French was transferred. When Hays took over the division Colonel George Willard took over his brigade. General Hays is honored at Gettysburg with a nearby monument.
