Two of von Gilsa's regiments, the 153rd Pennsylvania and 54th New York, had been placed up as a heavy skirmish line and the massive Confederate assault rolled completely over them. A few men managed to get off a shot or two before fleeing. The pair of artillery pieces at the very end of the XI Corps line were captured by the Confederates and promptly turned on their former owners. Devens's division collapsed in a matter of minutes, slammed on three sides by almost 30,000 Confederates. Col. Robert Reily and his 75th Ohio managed to resist for about ten minutes before the regiment disintegrated with 150 casualties, including Reily himself, and joined the rest of the fleeing mob.
