25th December Christmass Tuesday 
"I was awakened before Day by a discharge of 3 platoons from the Party and the french, the men merrily Disposed, I give them all a little Taffia [rum or spirits] and permited 3 Cannon fired, at raising Our flag, Some men went out to hunt & the Others to Danceing and Continued untill 9 oClock P,M, when the frolick ended &c."
Here "platoon" is used in its old sense of volleys, or a group of men firing in unison.
