After making the sketch... [of Fort McHenry], we returned, stopping on the way to make a drawing of the circular seven-gun battery..., and to find the sites of Fort Covington and the City Battery, which was commanded by the gallant Webster. These were situated on the river bank, below the circular battery, and nearly half a mile distant. Webster's battery was on a line with it, in the direction of the river, and Fort Covington was about five hundred yards farther up the stream. The circular battery was at the end of Light Street, that skirts Federal Hill, on which, at the time of my visit, were heavy earth-works, in charge of Duryee's Zouaves, thrown up as a protection to Fort McHenry against land attacks by insurgents. The mounds of the old circular battery were six or eight feet high in some places. It was in a commanding position. Our view, taken from within it, comprises the entire theatre of the operations of the British boat expedition on that eventful night. We are looking toward Chesapeake Bay. On the left is seen Fort McHenry, and in the extreme distance, appearing like a speck near the mouth of the Patapsco, is Fort Carroll.
