Major Vane, chief engineer for the Company, had tried all the mortars and coehorns, then fitted and stocked for the expedition.

Mr. John Minims was appointed chief engineer for the direction of these mortars and coehorns, which did great service.

The artillery consisted of two 24-pounders, two 18-pounders, four 9-pounders, six small field guns, two mortars, and eight coehorns.
