He was rather sceptical concerning the ability of the towing Tank to drag the crippled consort up the sloping side of the crater, but, to his delight, he found that he was mistaken. Choosing the easiest gradient, the Tank succeeded--not without considerable difficulty--in hauling her disabled sister out of the hole. The appearance of the latter was greeted by a round of cheering from the British infantry and a redoubled dose of "hate" from the infuriated Huns. Not until they were a mile behind their own lines, and sheltered from direct fire by a depression in the ground, did the two Tanks come to a standstill. "Why, you are Wheatshires!" exclaimed the lieutenant, as Setley and his comrades emerged from the armoured box. "What are you doing here?" "We got cut off, sir," replied Ralph, saluting. "We saw the Tank in the mine-crater, and we thought we could find cover there." "And you gave valuable assistance," rejoined the Tank officer, pulling out a notebook. "Give me your names and regimental numbers. It will be a pleasure to me to submit a report upon your gallant conduct in the work of rescue. No, I don't think you'd better try to rejoin your regiment at present. It isn't healthy out in the open. Better wait till after dark." "By Jove, Alderhame," exclaimed Ralph, after the officer had gone, "if ever I get a chance to serve in a Tank, I'm on!" "And this bird, too," added Alderhame. "No more foot-slogging infantry for me if there's a chance of riding in an armoured moving fort. Wonder how we could work it?" CHAPTER XI AN INTERVIEW WITH THE C.O. IT was close on midnight when Setley and his two companions rejoined their battalion. Although the distance was not far every foot of the way was beset with perils, for in spite of the heavier fire from the British guns the Germans were systematically searching the ground that had been wrested from them during the day. Every shell hole was now a miniature lake, covered with a thin coating of ice. A slip on the steeply sloping edge and the incautious wight would find himself out of his depth in icy cold water. The trio met a continuous procession of wounded, most of them having to be carried by their comrades or else on stretchers or sleighs; prisoners, too, who had been humanely kept under cover until darkness fell lest they should be shot down by their own guns, were being herded across the open--gaunt and hungry men who seemed glad to be out of the fighting. Ration and supply parties, units of ammunition columns passed to and fro, for the firing line had to be fed and provided with bombs and cartridges. Except for the absence of lights the traffic reminded Ralph of the Great North Road on the night of Barnet Fair, with the difference that the predominant colour-scheme was khaki everywhere.
