crest of the parapet rose eleven feet above the terre pleine and was 
twelve feet thick. It was surrounded by a dry ditch six feet deep and 
twelve feet wide, in the centre of which was planted a row of cedar 
pickets eleven or twelve feet high, while the exterior slope of the parapet 
was fraised with a similar row. A plan of the work, dated February, 
1812, filed in the Colonial Office, shows that at that time sixteen guns 
were mounted, of which one was a ten inch howitzer, nine were twenty- 
four pounders, four were field pieces mounted en barbette at the salient 
angles, and two were six pounders on field carriages. This number 
had been since increased to twenty-four, of which eleven, three twenty- 
four pounders, three brass six pounders, two four pounders, one three 
pounder, one 814, and one 514 mortar, were mounted on field carriages, 
probably for the contemplated attack upon Amherstburg, besides several 
wall pieces and swivels of small calibre. A detached blockhouse at 
the opposite angle of the stockade was armed with three six inch how- 
itzers, flanking the ditches in each direction. 
The effective strength of the garrison is difficult to ascertain. Hull, 
in his official letter, asserted that it did not exceed eight hundred, but 
this seems almost incredible. His actual losses in action had certainly 
not been great, nor had many become ineffective for garrison duty from 
disease. Allowing three hundred for losses from all causes during the 
campaign, four hundred of all ranks detached with McArthur, and two 
hundred Michigan militia stationed at the River Raisin, he must still 
have had at least sixteen hundred men available for the defence of his 
works. A very accurate account, published in the Montreal Gazette 
soon after, states the number of troops occupying the town and fort of 
Detroit at 1,826 of all ranks.?
