Colonel Leith: Royal Artillery, 357 men.
Of these, Brigadiers Havilland, Hunt-Walsh, and Lord Rollo had been employed in the reduction of the island of Martinique, and it will be noticed that a large proportion of the regiments had fought under Wolfe at Quebec, or Studholme Hodgson at the capture of Belleisle, or under Monckton at Martinique. Owing to the nature of the ground, considerable difficulty was experienced in constructing the siege batteries, which were armed with heavy guns from the fleet, the stores and ammunition being conveyed to the front by the corps of negroes purchased in Martinique by the General. In consequence of the scarcity and badness of the water, the troops suffered terribly. The seamen and Marines escaped the sickness which more than decimated the army, and the Admiral landed a body of 800 Marines to lighten the labours of the army.
On July 1 a heavy bombardment commenced, the fleet standing in to aid. In this the Dragon, Cambridge, and Marlborough suffered severely. For a time the fire of the defence slackened, only to be renewed with increased vigour in a couple of days. On the 21st the garrison made a gallant sortie, which was repelled with equal gallantry by the 90th Light Infantry, under Colonel Stuart. From this date the defence gradually slackened, and on July 30 the General determined to assault the Moro, which was the key of the situation. The storming-party, which was under the command of Colonel Stuart, of the 90th, was composed as follows:
| 1st Royal Scots | 6 | officers, | 107 | N.C.O.'s and men. |
| 90th Light Infantry | 8 | " | 53 | " |
| Marksmen | 8 | " | 29 | " |
the 35th Regiment in support. The assault was admirably planned, and carried out with dashing gallantry.
Casualties during the Expedition to Havana, from Date of Landing to Capitulation on August 13, 1762.
