Tuesday, 31st.—Warrenton has been badly torn up by shells, and the levee being cut, the water is about three feet deep all over town, but the houses being up on posts about four feet high, the water was not up into them. South of the town there is a vast expanse of water, covering several miles; have good house to stay in, the citizens all being away. Working on fort; only have to work four hours a day.
