这里更直接,解释了为什么会在那发生战斗

Gettysburg was a small, prosperous farming town. When a Southern brigade first passed through it, its commander noted that it contained a shoe factory. On June 30, a Confederate brigade had been sent to appropriate some of these shoes, but had withdrawn because of a large Federal force seen heading towards the town. The corps commander, Lieutenant General Hill, did not believe the Federals could be so near, and raised no objections when Major General Henry Heth, leading one of Hill's divisions, asked if he could use his superior force to collect some shoes. This was the spark that set off the battle.
