Arriving at the Great Fish River, the troops, guns, and baggage were ferried across on the India-rubber raft taken with the sappers, while the empty waggons were drawn over by means of a hawser. On the 20th the Orange River was reached; next day four other sappers were added to the party, and on the 22nd, at day-light, the India-rubber float was launched for the passage of the division. The river was 250 yards wide and a very rapid tide was running, when, having stretched a sheer line across the stream fastened on either shore to a tree, the operation was successfully carried out. Forty men were ferried across at a time, the expedient of the guiding hawser considerably lessening the labours of the party. Three guns and several waggons were also taken over. The latter were simply rolled on the raft without disturbing their loads, and were deprived of any dangerous motion by blocking their wheels. Not a single accident occurred; and in compliment to the unfailing zeal and efficiency of the men, Sir Harry Smith took occasion, on a general parade at Graham’s Town in October, 1848, to acknowledge that to the royal sappers and miners he was “greatly indebted for the means with which he had been enabled to make the passage of the Orange River, many of the men swimming in the river like dolphins in getting across the baggage and material.”[36] Marching for Boem Plaatz the detachment was present in an engagement with the Boers, remaining for a time in the rear in charge of ten ammunition tumbrils, and four engineer waggons, containing engineer tools and stores; but ordered to the front by the Governor’s aide-de-camp, Captain Holdich, they pressed forward with four ammunition waggons, and did good service, during the remainder of the action, by serving out the cartridges to the troops. It was not long before the Boers were beaten, and the column advanced, followed by the sappers and the train of waggons. The grass was on fire on either side of the road. Just at this time the fore-skean or linch-pin of the leading waggon broke, the near fore-wheel came off, and the tumbril upset. Another minute and the burning grass would have blown it up; but there were resolute spirits in the party, who, undaunted by the danger, rushed to the spot, raised the dismembered waggon from the fire, and replacing the wheel, fastened it by the drag-chain through the spokes to the tessel-boom. The expedient answered its purpose for twelve miles, when, by Sir Harry Smith’s orders, the ammunition was removed to a commissariat waggon.
