The hospital signal lights suspended over the island all night in order to direct the batteries where to aim their pieces in case of an outbreak which is greatly feared. Rockets sent up at intervals during the night over Richmond. Reported that there are six hundred muskets secreted among the prisoners and citizens very much alarmed and afraid of us. I hope there is but cannot believe it. It is impossible for me to sleep and I lay awake thinking how we are situated and wondering how long the play is to last.
