The prisoner's armour was certainly proof against fragments of bombs, even at close range, as the splayed marks upon the steel testified. With the anti-gas apparatus he had been able to withstand the choking fumes, until a chance splinter of metal had perforated the flexible pipe between the Hun's mouth and the oxygen-container hidden under his back-plate. Although his arms and legs were unprotected, the man had practically escaped injury from the bombs, since the fragments of the exploded missile flew upwards. A gash on the knuckle of his right hand and a few slight scratches on the calves of his legs were the total result of the Anzacs' efforts until the smoke-bomb came into play.
