On the 19th the Rebels took our hospital just outside our west line. The house was built of brick and afforded a good position for them to fire from the upper story. They fired directly into our trenches and after killing and wounding a number of our men. Genl Mulligan saw that they must be dislodged. He sent two companies of his Regiment down through our works on the charge to drive them out. They came along on the run and just as they emerged from our line of trench ... I joined them in the charge. We reached into the building and drove the enemy from the lower floor some of them running toward the river and some running up the stairs. They kept up a fire from the upper story and from the direction of the River so that many were killed and wounded of our party. After getting possession of the lower floor we were no better off than we would have been had we nothing at all of the house. I saw the officers trying to get their men to go up the broad stairway to drive the enemy from the upper story. With urging and ordering and threatening no one offered to take the lead up the stairs. It looked like a desperate attempt. I was now filled with dash and enthusiasm. I ran forward and jumped onto the second step of the stairs and turned to the men and said "If you will follow me I will lead you! We must drive them out!" They cheered and came forward like dear brave men as they were. And on we went with a yell and a rush. We went to the doors which were closed and locked. I knocked open one door with the butt end of my musket and stepped into the room, there were five Rebs there 2 of whom raised their guns to shoot me. I yelled at them to surrender which they at once did after seeing the men behind me. I had five prisoners and five guns. I took all the guns in my arms and ordered the prisoners to march.
