Very interesting string of posts. I had heard the Meade story before and have always wondered about it. Meade was on Cemetery Hill during the cannonade. I have cut and pasted the following from Double Canister at Ten Yards:
As he passed through the Evergreen Cemetery gate, he called out, "Major Osborn! Where is Maj. Osborn?" The high rate of artillery fire alarmed the army commander, who, according to eyewitnesses, was visibly upset. "Over here, General," Osborn is said to have called out in reply from an area near the gatehouse. Meade rode up to the dismounted major, and asked, "Don't you know that it is against general orders and military regulations to run out of ammunition during a battle?" Stunned, Osborn replied, "I never gave it much thought." This simple answer ignited Meade's famously short temper, "What do you intend to do at this position?" Shot back Meade. "I will hold this position if the infantry supports me," replied Osborn. "I don't think you will hold this position," shot back Meade, "but, since you intend to stay, watch your fire and make every shell count. Call on the reserve if you need ammunition."
