More troops poured into Harper's Ferry, and presently Colonel Robert E. Lee arrived with a force of United States marines. Guards were set about the engine-house to see that John Brown and his men did not escape. Then Colonel Lee sent a flag of truce to the engine-house, and in the name of the United States demanded that Brown surrender, advising him to throw himself on the clemency of the government. John Brown answered that he knew what that meant, and added, "I prefer to die just here." Again in the morning Lee sent his aide to the fort. The officer asked, "Are you ready to surrender, and trust to the mercy of the government?" Brown answered, "No, I prefer to die here." Then the soldiers attacked, not with guns this time, but with sledge-hammers, intending to break down the doors. This did not succeed, and seizing a long ladder they used it as a battering-ram, and finally broke the fastenings of the main door. Lieutenant Green pushed his way in, and, jumping on top of the engine, looked about for John Brown. Amid a storm of bullets, he saw the white-haired leader, and sprang at him, at the same time striking at him with his sword. John Brown fell forward, with his head between his knees. In a few minutes all of the raiders who were left in the engine-house had surrendered to the government troops. Of the band that had left the farm on Sunday night seven were taken prisoners, ten had been killed in the fighting, and six others had managed to make their escape. By noon of Tuesday, October 18th, the raid was over. John Brown, wounded in half a dozen places, lay on the floor of the engine-house; and the governor of Virginia bent over him. "Who are you?" asked the governor. The old man answered, "My name is John Brown; I have been well known as old John Brown of Kansas. Two of my sons were killed here to-day, and I'm dying too. I came here to liberate slaves, and was to receive no reward. I have acted from a sense of duty, and am content to await my fate; but I think the crowd have treated me badly. I am an old man. Yesterday I could have killed whom I chose; but I had no desire to kill any person, and would not have killed a man had they not tried to kill me and my men. I could have sacked and burned the town, but did not; I have treated the persons whom I took as hostages kindly, and I appeal to them for the truth of what I say. If I had succeeded in running off slaves this time, I could have raised twenty times as many men as I have now for a similar expedition. But I have failed."
