Mortars to reach the Town from their Lines, and from 22 to 26, for 
their long Rangers, but their lb. is heavier than Ours. 
Their Patroles come very near since the Sortée.” 
“5th December.—The Dons have picketted out a work in the Front of 
the Old M. Battery.” Mill Battery no doubt. The besiegers lost no 
time in reconstructing their works, and their progress was rapid, but no 
doubt the moral effect of the Sortie was great in both camps. 
“6th December.—No officer of the Line to presume to interfere in 
pointing a gun or give directions concerning it, but when on Guard if 
found necessary, they are to apply to the Artillery, who are there for 
that purpose.” 
The last entry in 1781-is as follows :— 
“29th December.—Last nt. died the Baron Helmstatt, Ensign in the 
Walloon Guards with the Rank of Captain and lost his Leg at the 
Mill Battery when taken Prisoner. A Flag of Truce to send his Body 
to the Camp, and it was escorted by the Grenadier Compy. 12th Regt. 
to the New Mole, where they fired 3 Rounds over it.” 
“ Ist January, 1782.—Our people are putting up the Cassons of 
Princess Ann’s Battery, Willis’s, before which they expose a curtain 
which the Dons have fired at.” 
“ Ist February.—Several stone Balls of different sizes found in the 
Ruins of the Moorish Castle, and Cells all over the yard. Fired Lieut. 
Koyler’s! depress Gun Carriage which answers from the Heights.” 
This carriage? was one invented by Lieut. Koehler, R.A., for firing 
from high sites at angles of considerable depression, up to 70° in fact. 
A description of it is to be found in Drinkwater’s history of the Siege, 
and Spilsbury gives several sketches of it. 
“ 4th February.—Our batteries are repairing with Ship Timber like 
Port Holes. They are making small Ditches in the Front of their 
Works, in case of another Sortée.” 
The following figures are for the year 1781. 
“ 10th February.—-The Dons computed expence of ammunition Shot 
102,084 ; Shells 28,943. Powder about 16,000 Barrels, a cwt. each. 
Our expence of Ammunition. 
About 1952 Barrels of Powder, and 46,010 Rounds of Shot, Shells, &c. 
“ 17th February.—About 1 a.m. asmall Brig from Ireland came off 
Kuropa and tho’ desired frequently to anchor near the other shiping she 
came to back Old Mole, and drove on shore—the Dons have fired about 
300 shots at her. ‘The Master deserved hanging for destroying other 
People’s property.” 
“ 4th March.—lIlt appears the Governor has ordered the Artillery not 
to make Reports or Returns to the Lieut.-Governor.” 
“ 29th March.—The Dons have blown off some of their guns, advanced 
work, and appear to be making a Lodgement by the Devil’s Town, and 
running a Communication to it from the Mill Battery.”
