During this campaign an incident occurred which well serves to show Lincoln's keen sense of justice, his great common sense, and his resoluteness when aroused. One day there came to the camp an old Indian, footsore and hungry. He was provided with a letter of safe-conduct from General Cass; but there was a feeling of great irritation against the Indians, and the men objected strongly to receiving him. They pronounced him a spy and his passport a forgery, and were rushing upon the defenseless Indian to kill him, when the tall figure of their captain, Lincoln, suddenly appeared between them and their victim. His men had never seen him so aroused, and they cowed before him. "Men," said he, "this must not be done! He must not be killed by us!" His voice and manner produced an effect on the mob. They paused, listened, fell back, and sullenly obeyed him, although there were still some murmurs of disappointed rage. At length one man, probably thinking he spoke for the crowd, cried out: "This is cowardly on your part, Lincoln!" Lincoln only gazed with contempt on the men who would have murdered one unarmed Indian but who quailed before his single hand. "If any man thinks I am a coward," said he, "let him test it." "Lincoln," was the reply, "you are larger and heavier than any of us." "That you can guard against," responded the captain. "Choose your weapons!" The insubordination ended, and the word "coward" was never associated with Lincoln's name again. He afterward said that at this time he felt that his life and character were both at stake, and would probably have been lost had he not at the supreme moment forgotten the officer and asserted the man. His men could hardly have been called soldiers. They were merely armed citizens, with a military organization in name only. Had he ordered them under arrest he would have created a serious mutiny; and to have them tried and punished would have been impossible.
