Once again, just before twilight, the battle burst out on both sides with tremendous fury. The whole valley was hidden in clouds of smoke and dust, and flashes of fire and puffs of smoke flew up from the ground on all sides. Then evening came and, bit by bit, it grew more quiet as one battery after the other ceased firing. The shrill whistle of an engine came from the mountain-pass. And now, from far away, the Japanese bugle-call sounded through the silent starry night and was echoed softly by the mountain-sides, warming the hearts of all who heard it: [line of music] _Chapter XIX_ THE ASSAULT ON HILGARD It was three o'clock in the morning. Only from the left wing of Fowler's Division was the booming of cannon occasionally heard. From the mountain-pass above came the noise of passing trains, the clash of colliding cars and the dull rumble of wheels. On the right all was still. A low whistle went through all the trenches! And then the regiments intended for the assault on Hilgard crept slowly and carefully out of the long furrows. The front ranks carried mattresses, straw-bags, planks and sacks of earth to bridge the barbed wire barricades in case they should not succeed in chopping down the posts to which the wires were fastened. A few American batteries behind La Grande began firing. The other side continued silent. Suddenly two red rockets rose quickly one after the other on the right near the mountain, and they were followed directly by two blue ones; they went out noiselessly high up in the air. Was it a signal of friend or foe? The regiments came to a halt for a moment, but nothing further happened, except that the two searchlights beyond Hilgard kept their eyes fixed on the spot where the rockets had ascended. A dog barked in the town, but was choked off in the middle of a howl. Then death-like stillness reigned in front once more, but several cannon thundered in the rear and a few isolated shots rang out from the wooded valleys on the left. The front ranks had reached the wire barricades. Suddenly a sharp cry of pain broke the silence and red flames shot forth from the ground, lighting up the posts and the network of wires. Several soldiers were seen to be caught in the wires, which were apparently charged with electricity. Now was the time! The pioneers provided with rubber gloves to protect them against the charged wires went at it with a vengeance, and were soon hacking away with their axes. Loud curses and cries of pain were heard here and there. "Shut up, you cowards!" yelled some one in a subdued voice. The black silhouettes of the men, who were tossing long boards and bags of earth on top of the wires, stood out sharply against the light of the explosives with which the Americans were attempting to loosen the supporting posts.
