Altogether, there were 4 officers, 20 Australians, and 15 Riflemen. One of the Australians, named McGrady, was particularly cool and helpful, but was unfortunately killed before the party reached safety. Even at this crisis the military code was strictly observed, and the confidential documents of the battalion carefully destroyed by the adjutant. As the British emerged into the gloom from one end of the tunnel, a party of Germans began to enter at the other, but were so skilfully delayed by two Riflemen, acting as rearguard, that they were unable to stop the retreat. The men streamed out at the farther end under the very noses of their enemies, and crept swiftly in small parties down to the river, which at this point is from 70 to 100 yards broad. Across their path lay a camouflage screen some twelve feet high, which had been set on fire by the shells. It was a formidable obstacle, and held them up for some time, but was eventually crossed. Here they were faced by the problem of the broken bridges, and several were shot while endeavouring to find some way across. Finally, however, the swimmers helping the others, the greater number, including the four Rifle officers, got safely across, being nearly {129} poisoned by gas shells as they landed upon the farther side. Of the Northamptons, it would appear that only one officer, Captain Martin, made his escape, though badly wounded. Colonel Tollemache was heard calling out to his men: "It may be the last time, but fight like Englishmen!" He and all his staff became casualties or prisoners. The Northampton front was not more than forty yards from that of the Germans, and the rifle-fire of the latter swept the parapet to such an extent that it was impossible to stop the rush. A private who was No. 1 of a machine-gun, with two other men, who knew nothing of the mechanism, rushed a gun out upon the flank and held up the grey wave for a minute or so before being submerged, while a sergeant also distinguished himself by a determined resistance and by finally crossing the Canal to explain the situation to those in command there.
