This was in the rain-scourged autumn of 1916, when the unspeakable desolation of the Somme battlefield was a sea of mud. The ruins of the villages—Ovillers, La Boisselle, Pozières, Courcelette, Martinpuich, and all the others which had once made fair with flowers and orchards this rolling plateau of Picardy—had been pounded flat by the inexorable guns, and were now mere islands of firmer ground in the shell-pitted wastes of red mire. Men went encased in mud from boots to shrapnel helmet. And it was a special mud of exasperating tenacity, a cement of beaten chalk and clay. The few spidery tram-lines ran precariously along the edges of the shell-holes, out over the naked, fire-swept undulations beyond Mouquet Farm and Courcelette, where they were continually being knocked to pieces by the “whizz-bangs,” and tirelessly rebuilt by our dauntless pioneers and railway troops. Scattered all about this dreadful naked waste behind our front trenches lurked our forward batteries, their shallow gun-pits cunningly camouflaged behind every little swell of tumbled mud.

This foul mud, hiding in the deep slime of its shell-holes every kind of trap and putrid horror, was the appropriate ally of the Germans. Stinkingly and tenaciously and treacherously, as befitted, it opposed the feeding of the guns. Two by two or four by four, according to their size, the shells for the guns had to be carried up from the forward dumps in little wicker panniers slung across the backs of horses and mules. It was a slow process, precarious and costly, but it beat the mud, and the insatiable guns were fed.

After the night when the mule-lines at Aveluy were shelled, the big black mule and his driver were put on this job of carrying up shells to the forward batteries. The driver, a gaunt, green-eyed, ginger-haired teamster from the lumber camps of Northern New Brunswick, received the order with a crooked grin.

“Say your prayers now, Sonny,” he muttered in the mule’s big, waving ear, which came to “attention” promptly to receive his communication. “You’ll be wishing you was back in them old lines at Aveluy afore we’re through with this job. Fritzy over yonder ain’t goin’ to like you an’ me one little bit when he gits on to what we’re up to. It ain’t like haulin’ fodder, I tell you that. But I guess we’ve got the nerve all right.”

Instead of rolling the whites of his eyes at him, in surly protest against this familiarity, the black mule responded by nibbling gently at the sleeve of his muddy tunic.

“Geezely Christmas,” murmured the driver, astonished at this evidence of goodwill, “but it’s queer, now, how a taste o’ shell-fire’ll sometimes work a change o’ heart, even in an Argentino mule. I only hope it’ll last, Sonny. If it does, we’re goin’ to git along fine, you an’ me.” And the next time he visited the canteen he brought back a biscuit or two and a slab of sweet chocolate, to confirm the capricious beast in its mended manners.

Early that same afternoon the black mule found himself in new surroundings. He was at the big ammunition dump which lay concealed in an obscure hollow near the ruins of Courcelette. He looked with suspicion on the wicker panniers which were slung across his sturdy back. Saddles he knew, and harness he knew, but this was a contraption which roused misgivings in his conservative soul. When the shells were slipped into the panniers, and he felt the sudden weight, so out of all proportion to the size of the burden, he laid back his long ears with a grunt, and gathered his muscles for a protesting kick. But his driver, standing at his head, stroked his muzzle soothingly and murmured: “There, there, steady, Son! Keep your hair on! It ain’t goin’ to bite you.”

Thus adjured, he composed himself with an effort, and the lashing kick was not delivered.

“What a persuasive cuss you must be, Jimmy Wright!” said the man who was handling the shells. “I wouldn’t trust you round with my best girl, if you can get a bucking mule locoed that way with your soft sawder.”

“It ain’t me,” replied the New Brunswicker. “It’s shell-shock, I guess, kind of helped along with chocolate an’ biscuits. He got a bit of a shaking up when they shelled the lines at Aveluy night afore last, an’ he’s been a lamb ever since. Seems to think I saved his hide for him. He was the very devil to handle afore that.”
