Even since the battle at Antietam, the Lower Bridge has been called Burnside Bridge.
Confederate Colonel Douglas was a native of Sharpsburg, and familiar with Antietam Creek. After the war he wrote:
"Go look at it and tell me if you don't think Burnside and his corps might have executed a hop, skip, and jump and landed on the other side. One thing is certain, they might have waded it that day without getting their waist belts wet in any place. Why Burnside's Bridge? It is sarcasm?"
The 51st New York and the 51st Pennsylvania captured Lower Bridge about 1 p.m. The Union Ninth Corps spent the next two hours preparing for the final assult on Sharpsburg:
"The troops commenced crossing and a continuous stream of infantry and artillery poured over the bridge during the afternoon."
By 3 p.m. Ninth Corps was ready.
All except our second division were sent forward and attacked the enemy's right flank, which if done earlier in the day, when the enemy's left and center were engaged might have destroyed Lee's army."
"It is General Burnside's special request that the two 51st's take that bridge. Will you do it?"
A Pennsylvania soldier called out:
"Will you give us our whiskey, Colonel, if we make it?"
"Yes, by God!"
The two 51st's, New York on the left and Pennsylvania on the right,
..."charged up the road in column with fixed bayonets, and in scarcely more time than it takes to tell it the bridge was passed."
They got their whiskey.
