The brigade at 10:30 a.m. took position to the right of Corse's Brigade and co-operated with it till the termination of its assault. About 1 p.m., with its left on the Tunnel Hill Road north of the Glass House, and supported by Buschbeck's Brigade, it moved toward the mouth of the tunnel, its skirmishers carrying the position about the Glass House, and part of the main line reaching the railroad. The 27th and 73rd Pennsylvania of Buschbeck's Brigade then advanced to Loomis' left and pushed the Confederates back to their works over the tunnel. Matthies' Brigade next came up on Loomis' left and charged to the summit of the ridge where it formed on the right and left of the 27th Pennsylvania that had preceded it, followed by Raum's Brigade. The entire force was finally repulsed by charges from the crest, and a flank movement from the tunnel. At 4 p.m. the brigade was withdrawn.
