Sunday, the 6th September.—The English and Dutch men-of-war sent on shore about forty gunners to assist at our batteries, and the Danish regiments sent several officers skilled in fireworks to help our bombarding, the batteries for our mortars being now ready, as also a battery of sixteen twenty-four pounders, besides another of six, very much advanced. The general ordered colonel Goor to keep in readiness eight field-pieces and all the pontoons, that in the night we might fling a bridge over the river. The mortars now in batteries are two of eighteen inches, three of thirteen inches, and three of ten inches, besides two of ten inches taken out of the 'Salamander,' bomb ketch.
