Battle of Cross Keys

The regiment was on the right of Stahel’s Brigade. It supported a battery for four hours under heavy shelling until it was discovered that Fremont had withdrawn the army, although no orders reached the 27th Pennsylvania. Confederates had worked their way in behind the regiment, so Colonel Bushbeck faced the regiment about and drove the enemy away to make his escape, bringing away the battery and their wounded. To add insult to injury the regiment was fired upon as they tried to rejoin Fremont’s army, since it was assumed they had been captured. But when the the confusion was cleared up General Fremont thanked the regiment for saving the battery and cutting its way out of its entrapment.

The regiment lost one officer and 14 men killed, and 3 officers and 87 men wounded.

Battle of Chancellorsville

Battle of Chancellorsville – Day 2

The 27th Pennsylvania’s brigade was detached to support Sickles’ Third Corps and was on the left of the 11th Corps when Jackson’s devastating attack hit the rest of the 11th Corps that afternoon. Bushbeck ordered the 27th Pennsylvania and 29th New York to redeploy in the path of the attack. But they were badly outnumbered and outflanked and were forced into a fighting retreat back to the Chancellor House. The 11th Corps line reformed there and held in the face of the final Confederate attacks. Bushbeck’s stand earned praise even from those who were critical of the German troops of the Eleventh Corps.

On reaching Gettysburg the 27th Pennsylvania was ordered to take possession of the jail, church, and school building at one end of the town and make preparations to defend against attack from that direction.

Two Eleventh Corps Divisions had meanwhile been sent north of the town to set up a defensive line. The line had been heavily attacked and was collapsing, and the 27th Pennsylvania was ordered to advance to fill a dangerous gap in the line. In the confusion only about fifty men under the command of Lieutenant Vogelbach reached the position, and they were flanked on both sides and forced to retreat. They were soon cut off, and in an attempt to cut their way out Lieutenant Vogelbach was killed and the survivors surrendered. The survivors of the regiment retreated to Cemetery Hill and was posted behind a stone wall along Baltimore Pike.
