It's difficult for me to understand why Heth would send his men to raid a large shoe store. Whatever inventory the store had in stock, it would not make up for the shoe leather lost by the men on that march. A quartermaster and a few men with an empty wagon would have sufficed. It also does not give much credit to Early's men who passed that same store five days earlier, and a senior Confederate officer should have guessed that valuable merchandise would have been removed to a distant location when word came of the invasion. Incidentally, Gettysburg was well known for making carriages, not shoes. So there must be another motive. Perhaps Heth expected to bag some militia units with a show of overwhelming force, then he could have taken their shoes, like Early did with the 26th Pennsylvania Emergency Militia.
