Dawn on the Western Front. Everything is in readiness for a great infantry attack. For weeks past the preparations have been in progress. The roads leading to the front have been ground to powder by the endless processions of heavy-laden motor-lorries bringing up food, ammunition, and supplies. The advanced dumps are piled high with cases of rifle and machine-gun cartridges, trench-mortar ammunition, shell of every calibre and kind, all stencilled with the flaming bomb which is the trade-mark of the Army Ordnance. Up in the forward observation-posts intelligence officers are peering anxiously through periscopes into the fog-hung wastes of No Man’s Land. In the assembly trenches the storm troops are waiting in silence on the tapes which mark the positions of the various units, the faces of the men showing grim and determined under their steel helmets. Each wears a belt containing a hundred cartridges in clips; his bayonet is fixed. The men of the medical detachments, distinguished by the broad-bladed bolos at their hips, lean against their up-ended stretchers, waiting for the beginning of the bloody business which will stain those stretchers red. The officers, a trifle nervous and self-conscious, stroll up and down the ranks, examining their automatics or glancing at the luminous dials of their wrist-watches to note the approach of the zero hour. Rifles, bayonets, pistols, bolos, periscopes, cartridges, together with the clips which hold them and the belts in which they are carried—all are ordnance.
