And after the trench was more or less repaired came the last and the most desperate business of all--the 'wiring' out there in the open under the eye of the soaring lights. In ones and twos during the intervals of darkness the men tumbled over the parapet, dragging stakes and coils of wire behind them. They managed to drive short stakes and run trip-wires between them without the enemy suspecting them. When a light flamed, every man dropped flat in the mud and lay still as the dead beside them till the light died. In the brief intervals of darkness they drove the stakes with muffled hammers, and ran the lengths of barbed wire between them. Heart in mouth they worked, one eye on the dimly seen hammer and stake-head, the other on the German trench, watching for the first upward trailing sparks of the flare. Plenty of men were hit of course, because, light or dark, the bullets were kept flying, but there was no pause in the work, not even to help the wounded in. If they were able to crawl they crawled, dropping flat and still while the lights burned, hitching themselves painfully towards the parapet under cover of the darkness. If they could not crawl they lay still, dragging themselves perhaps behind the cover of a dead body or lying quiet in the open till the time would come when helpers would seek them. Their turn came when the low wires were complete. The wounded were brought in cautiously to the trench then, and hoisted over the parapet; the working party was carefully detailed and each man's duty marked out before they crawled again into the open with long stakes and strands of barbed wire. The party lay there minute after minute, through periods of light and darkness, until the officer in charge thought a favourable chance had come and gave the arranged signal. Every man leaped to his feet, the stakes were planted, and quick blow after blow drove them home. Another light soared up and flared out, and every man dropped and held his breath, waiting for the crash of fire that would tell they were discovered. But the flare died out without a sign, and the working party hurriedly renewed their task. This time the darkness held for an unusual length of time, and the stakes were planted, the wires fastened, and cross-pieces of wood with interlacings of barbed wire all ready were rolled out and pegged down without another light showing. The word passed down and the men scrambled back into safety. 'Better shoot a light up quick,' said the Engineer officer to the infantry commander. 'They have a working party out now. I heard 'em hammering. That's why they went so long without a light.' A pistol light was fired and the two stared out into the open ground it lit. 'Thought so,' said the Engineer, pointing. 'New stakes--see? And those fellows lying beside 'em.'
