But the detachment was already so placed that nothing could save it from heavy loss. The wagons had all passed but nine, and the leading battery of artillery was at the very edge of the donga. Nothing is so helpless as a limbered-up battery. In an instant the teams were shot down and the gunners were made prisoners. A terrific fire burst at the same instant upon Roberts's Horse, who were abreast of the guns. 'Files a bout! gallop!' yelled Colonel Dawson, and by his exertions and those of Major Pack-Beresford the corps was extricated and reformed some hundreds of yards further off. But the loss of horses and men was heavy. Major Pack-Beresford and other officers were shot down, and every unhorsed man remained necessarily as a prisoner under the very muzzles of the riflemen in the donga. As Roberts's Horse turned and galloped for dear life across the flat, four out of the six guns [Footnote: Of the other two one overturned and could not be righted, the other had the wheelers shot and could not be extricated from the tumult. It was officially stated that the guns of Q battery were halted a thousand yards off the donga, but my impression was, from examining the ground, that it was not more than six hundred.] of Q battery and one gun (the rearmost) of U battery swung round and dashed frantically for a place of safety. At the same instant every Boer along the line of the donga sprang up and emptied his magazine into the mass of rushing, shouting soldiers, plunging horses, and screaming Kaffirs. It was for a few moments a sauve-qui-peut. Serjeant-Major Martin of U, with a single driver on a wheeler, got away the last gun of his battery. The four guns which were extricated of Q, under Major Phipps-Hornby, whirled across the plain, pulled up, unlimbered, and opened a brisk fire of shrapnel from about a thousand yards upon the donga. Had the battery gone on for double the distance, its action would have been more effective, for it would have been under a less deadly rifle fire, but in any case its sudden change from flight to discipline and order steadied the whole force. Roberts's men sprang from their horses, and with the Burmese and New Zealanders flung themselves down in a skirmish line. The cavalry moved to the left to find some drift by which the donga could be passed, and out of chaos there came in a few minutes calm and a settled purpose.
