September 15, 1916, began as a routine day for the German infantrymen in the forward trenches around Flers on the Somme—as routine as any day was likely to be after two and a half months of vicious, close-gripped fighting that bled divisions white and reduced battalions to the strength of companies. True, an occasional rumble of engines had been audible across the line. But the British had more trucks than the Kaiser’s army, and were more willing to risk them to bring up ammunition and carry back wounded. True, there had been occasional gossip of something new up Tommy’s sleeve: of armored “land cruisers” impervious to anything less than a six-inch shell. But rumors—Scheisshausparolen in Landser speak—were endemic on the Western Front. Then “a forest of guns opened up in a ceaseless, rolling thunder, the few remaining survivors . . . fight on until the British flood overwhelms them, consumes them, and passes on. . . . An extraordinary number of men. And there, between them, spewing death, unearthly monsters: the first British tanks.”
Improvised and poorly coordinated, the British attack soon collapsed in the usual welter of blood and confusion. But for the first time on the Western Front, certainly the first time on the Somme, the heaviest losses were suffered by the defenders. Reactions varied widely. Some men panicked; others fought to a finish. But the 14th Bavarian Infantry, for example, tallied more than 1,600 casualties. Almost half were “missing,” and most of them were prisoners. That was an unheard-of ratio in an army that still prided itself on its fighting spirit. But the 14th was one of the regiments hit on the head by the tanks.
Shock rolled uphill. “The enemy,” one staff officer recorded, “employed new engines of war, as cruel as effective. . . . It is necessary to take whatever methods are possible to counteract them.” From the Allied perspective, the impact of tanks on the Great War is generally recognized. The cottage industry among scholars of the British learning curve, with descriptions of proto-mechanized war pitted against accounts of a semi-mobile final offensive based on combined arms and improved communications, recognizes the centrality of armor for both interpretations. French accounts are structured by Marshal Philippe Petain’s judgment that, in the wake of the frontline mutinies of 1917, it was necessary to wait for “the Americans and the tanks.” Certainly it was the tanks, the light Renault FT-17s, that carried the exhausted French infantry forward in the months before the armistice. Erich Ludendorff, a general in a position to know, declared after the war that Germany had been defeated not by Marshal Foch but by “General Tank.”
