The monitor “Mahopac”The monitor “Mahopac,” as she floated in the James near Bermuda Hundred in 1864, illustrates one of the newer types completed in 1864. The lower picture gives a good idea of her deck. The gun-ports of her turret are open. The coffin-like hatchway in the foreground was the only means of entrance. In action or rough weather this was tightly closed. Air-holes with their gratings are seen at intervals about the deck, but these too had to be closed during a storm. It was almost a submarine life led by the officers and crew in active service. Every opportunity was seized to get above deck for a breathing space. The “Mahopac” had a crew of 92 men. Her first engagement was with Battery Dantzler in the James River, Nov. 29, 1864. In December, 1864, and January, 1865, the “Mahopac” was in the first line of the ironclads that bombarded Fort Fisher. Her men declared that she silenced every gun on the sea-face of that fort.
