But Lawrence’s heart sank as he saw his devoted little band becoming less and less. He had no reserves. There was no limit to the number that the enemy could throw against him. The crowd on the bridge never diminished. As soon as one man fell his place was taken from behind. From sheer exhaustion the defenders could not stem the torrent many minutes longer. Their arms were aching and numbed almost to the point of paralysis. The frequent alarms and broken rest of seven days and nights were telling on their hardy frames. Lawrence, swinging his rifle like a flail, expected at every stroke that his muscles would refuse to lift the weapon for another. Missing Bob’s cheering cries, he gave a rapid glance round, and seeing his brother on the ground, he was just making up his mind that the time had come for a general retreat to the galleries, their last line of defence, when there came the sudden crackle of rifles from a new direction. It was on the right. There was a cheer, very different from the shrill cries of the Kalmucks, and then confused cries all around. The firing from the rocks had ceased. At a second volley the Kalmucks on the bridge halted in surprise and hesitation. Lawrence guessed what had happened. Seizing the moment, he shouted to his men to follow him, and springing from the wall, led them in a fierce rush on to the bridge. They swept the enemy before them, cutting down one, tumbling another into the stream. On the track a disorderly terrified crowd were rushing past the bridge towards the north, masking the fire of their own guns at the bend. Behind them at a gallop came fifty sowars of the Border force, led by Major Endicott himself. They swept on through the panic-stricken mob, upon whom, as the horsemen passed, the garrison from their post on the bridge opened a withering fire. Major Endicott and his troopers pushed on and on, driving the enemy, some before them, some into the river, some up the rugged hillside. They did not halt until they reached the guns. There were a few minutes of desperate fighting about them; then the gunners were cut down, and the swarms behind were in full flight down the track. At a word from the Major half the sowars leapt from their horses, slewed the guns round, and sent shell after shell among the frenzied crowd until the whole track within sight was clear of living men. And Bob woke to consciousness to hear his brother’s voice lead the men in a ringing cheer. The mine was saved; the enemy had been held in check for a week; every man had done his duty. CHAPTER THE TWENTY-NINTH REUNION Major Endicott left his men at the bend, and galloped back to the bridge. Dismounting there, he pressed Lawrence’s hand warmly. "Well played, sir!" he said. "Where’s your brother?" "In the compound, Major. He’s all right, I think: that is, he wasn’t hit this morning; but he was wounded yesterday, and is rather off colour."
