1. The previous Saturday was 1 November.
2. “We are now making two floating batteries up the Schuylkill intending to act against the fort,” wrote Royal Artillery officer Francis Downman in his journal entry for 31 October. “This should have been done a month ago, but as in everything else we act like snails. We have no spunk; neither life nor spirits appears in anything we do. By our delays and trifling attempts we point out to the rebels where their works are deficient and give them time to complete them” (Whinyates, Services of Francis Downman description begins F. A. Whinyates, ed. The Services of Lieut.-Colonel Francis Downman, R.A., in France, North America, and the West Indies, between the Years 1758 and 1784. Woolwich, England, 1898. description ends , 48). On 3 Nov. Downman wrote that “things seem to be preparing for a little fun. Our ships are nearer the chevaux-de-frise than usual. Two floating batteries for 32–prs. are in forwardness, and fascines and planks are ready for the batteries. . . . Lord Howe intends fitting out two or three vessels with large guns to act with the others now making ready. Less than a week will determine who is to be master of the river Delaware” (ibid.). Two floating batteries apparently were launched on 6 Nov., when one of them sank, and a third was launched several days later (see Charles Craig to GW, 8 Nov., and note 1, and James Mitchell Varnum to GW, 9 Nov.).
3. Boon Dam was near Carpenter’s and Province islands, probably on Boon’s (Boone, Boane) Creek.
