Three months later the troops were rotated again:11
The troops in garrison changed quarters on the 21st: the 39th and Hardenberg's regiments relieved the 72d, and other detachments in King's and Montague's bastions, Waterport-casemate, and Picquet-yard. The 58th, 72d, and 73d regiments encamped; the 12th regiment remained on their ground; and the 56th, Reden's, and La Motte's, occupied the South barracks, and other quarters.
Despite the distance from the main Spanish batteries over 3.5 km away, the barracks was not immune to shell fire, nor from being harassed by mortar fire from the swarm of gunboats that approached the area of Rosia under cover of night. Both Drinkwater and Spilsbury recall how one shell fired from the Mill Battery in the isthmus, landed in the middle yard of South Barracks. Drinkwater adds that a splinter of this shell flew to the Naval Hospital.12
In September, Drinkwater again reported that:13
The evening of the 7th, the Captain at Willis's again endeavoured to set fire to the weeds, &c. in the gardens, which from their height afforded great cover to the Enemy's advanced sentries; and in executing these orders a brisk cannonade was returned by the Enemy, which continued till day-break… In the course of this firing, several shot from the Lines ranged as far as the South barracks and New mole….
Spilsbury also notes several shots landing in the South Barracks:
6th [July]. Wind the same. P.M. A shot came from Fort Phillip to the middle yard South Barracks, and buried itself 5 feet in the ground.14
19th, [Nov] Wind the same. The Dons throw long rangers now, from the Mill Battery, all about the South Barracks.15
Drinkwater summarized the reasons for such long-ranged shells as follows:16
In the forenoon of the 16th, a long-ranged shell, from the St. Carlos’s battery, burst in the air over Hardy town, and a splinter of it flew into the sea, beyond Buena-Vista, a distance of more than three miles. Another shell fell, in the course of the morning, at the foot of a wine-house, south of the barracks; and several burst high in the air over south shed. We attributed these uncommon long ranges to the force of the wind, which, blowing in the same direction in which the shells were thrown, undoubtedly increased their velocity.
Despite the damage inflicted on such a large and obvious target, the artificers continued to repair the barracks and on the 27th April 1782, Spilsbury records in his diary that a clock was put up at South Barracks.17
