In the attack on Fort Beaufort in which Hermanus was killed, corporal Castledine was posted with seven sappers in charge of a tower where the ammunition was kept, and commanded a 24-pounder howitzer mounted on it. The post of honour was given to this trustworthy non-commissioned officer in anticipation of an attack from Sandilli, who showed in force on the opposite side of the town. At the commencement of the action corporal Castledine was nominated to be garrison sergeant-major, and held the appointment until ill health compelled him to resign. This occurred in February, 1852, when Major-General Somerset, in a division order, acknowledged that “corporal Castledine had performed its arduous duties with the highest credit.” Colonel Sutton, for many months, was the only officer at Fort Beaufort, and on many occasions, when the nature of the service required his presence elsewhere, corporal Castledine commanded the garrison in his absence. Often he had to send escorts of provisions and ammunition to supply General Somerset’s division, which service was always so satisfactorily performed that both the General and Colonel Sutton repeatedly commended him for his judgment, promptitude, and zeal. Five rank and file attached to Captain Tylden, R.E., employed surveying in the territory of the chief Mapassa, being interrupted in the duty, were now necessarily occupied in adopting expedients for protection. Early in the year they assisted the inhabitants of Whittlesea in strengthening their houses against attack, and in converting the village into a strong defensible position. Afterwards they constructed a small musket-proof redoubt of dry stones, twelve feet square, with walls three feet thick and seven high, round their own camp, to protect the field guns, military stores, and equipment. The waggons were also brought into requisition, and stone walls were built up under them to render them defensible. By the evening of the second day everything was completed. Into this miserable post the Captain with his five sappers, one officer, a sergeant of police and his wife and four children, took refuge. The sappers worked so hard during the day that the Captain had to take his turn at sentry during the night.[61] Soon after these precautionary services, repeated actions took place between the garrison with the levied troops raised by Captain Tylden, and the neighbouring tribes, in every one of which, though attacked by an immensely-superior force, the little band beat off their assailants with severe loss, and gained for it the admiration and thanks of the General commanding-in-chief. The desperation and difficulties of their isolation, coupled with the paucity of their numbers, whetted their spirit of enterprise, and though their endurance and heroism might be equalled, they could never be excelled. In all the operations at Whittlesea, and in the actions with the tribes at adjacent places, as many of the few sappers as could be
