As soon as the news of the enemy’s evacuation reached Lukin, he dispatched the Duke of Westminster with the armoured cars in pursuit. The battery consisted of nine cars and one open Ford car mounting a machine gun, and the total _personnel_ was only thirty-two. They made for the enemy’s camp at Bir Warr, where a straggler was captured, who was afterwards to prove a most valuable prize. Dashing along the Tabruk road, which runs westward into the Libyan desert, they came presently upon the _débris_ of the retreat. After 23 miles had been covered, the leading cars, as they turned a bend in the road, came suddenly in view of the enemy’s camp at the Bir Asisa well a few hundred yards to the south. The camels were standing loaded, one ten-pounder and two machine guns were in position, and the enemy masses were just beginning to move. The battery swung into line and charged. Their machine guns silenced the Turkish guns, and the shells from the ten-pounder burst far behind them. The Senussi were surprised and wholly demoralized. Most of them flung down their rifles and fled. To prevent the escape of the supply train some 50 camels already on the move were shot—in several cases with extraordinary results, for the unhappy beasts were laden with petrol and bombs, and blew up under our fire with terrific explosions. At least 50 of the enemy were killed, 40 prisoners were taken, including 3 Turkish officers, and all the Senussi guns and much of the supplies were captured. The British loss in this brilliant affair was one officer slightly wounded. [Sidenote: _Mar. 17._]
