The advance was very distressing, and the troops suffered much. The badness of the roads, the heat of the weather, and worse still, the scarcity of water, was severely felt before the brigades, at a late hour, reached their bivouacs in Reit Valley, a farming establishment belonging to the Dutch government. Here some salt provisions, which had been floated through the surf, were brought up by the marines, and partitioned among the soldiers; while the few and scanty springs attached to the farm afforded them an indifferent supply of water. An immediate movement on the capital was imperative; and the next day the British reached a position beside the Salt River--an inlet some short distance from the strong lines which cover Cape Town. These defences are formed of a chain of redoubts, with a connecting parapet, furnished with banquettes[39] and a dry-ditch. They extend about eight hundred yards, and unite the Devil’s Berg with the sea. These lines were very formidable, as they had been considerably strengthened by the English during their possession of the colony. One hundred and fifty guns and howitzers were mounted on the works; and several batteries had been erected on the escarpe of the mountain, that would have exposed assailing troops to a flanking fire, and, in storming the lines, occasioned a severe loss of life. One battery and blockhouse were placed on a shoulder of the hill, thirteen hundred feet above the level of the plain. But this was probably the least effective of the defences; as, in modern warfare, a plunging fire is not regarded much. A mile behind the lines the castle of Good Hope is situated at the entrance of the town. It is a pentagon, with outworks strong enough to require a regular approach; and that side of the city which overlooks the bay is secured alike by the fire of the castle, and a number of batteries mounted with guns of heavy calibre. To carry works so extensive, and so formidable in their defences, with a small corps like Baird’s, unprovided with any artillery but the light field-pieces they had brought through the sands, was not to be attempted; and it was determined to obtain some heavy guns, and a reinforcement of seamen and marines from the fleet. But these were not required: the enemy sent out a flag of truce, and an armistice was agreed upon, which terminated ultimately in a capitulation. The town and its defences were given up to the British army, and, without a shot, works were surrendered to a force of not four thousand men, on which were mounted four hundred and fifty-six guns and mortars, most of them of the heaviest calibre.
