As the troops left the fort, the band struck up the Dead March. On they came in military array, but with solemn mien. Captain Wells took the lead at the head of his little band of Miamis. He had blackened his face before leaving the garrison, in token of his impending fate. They took their route along the lake shore. When they reached a point where commenced a range of sand-hills intervening between the prairie and the beach, the escort of Pottowattamies, in number about five hundred, kept the level of the prairie, instead of continuing along the beach with the Americans and Miamis.
They had marched perhaps a mile and a half, when Captain Wells, who had kept somewhat in advance with his Miamis, came riding furiously back.
"They are about to attack us," shouted he; "form, instantly, and charge upon them."
Scarcely were the words uttered, when a volley was showered from among the sand-hills. The troops were hastily brought into line, and charged up the bank. One man, a veteran of seventy winters, fell as they ascended. The remainder of the scene is best described in the words of an eye-witness and participator in the tragedy, Mrs. Helm, the wife of Captain (then Lieutenant) Helm, and step-daughter of Mr. Kinzie.
"After we had left the bank the firing became general. The Miamis fled at the outset. Their chief rode up to the Pottowattamies and said:
"'You have deceived the Americans and us. You have done a bad action, and (brandishing his tomahawk) I will be the first to head a party of Americans to return and punish your treachery.' So saying, he galloped after his companions, who were now scouring across the prairies.
"The troops behaved most gallantly. They were but a handful, but they seemed resolved to sell their lives as dearly as possible. Our horses pranced and bounded, and could hardly be restrained as the balls whistled among them. I drew off a little, and gazed upon my husband and father, who were yet unharmed. I felt that my hour was come, and endeavored to forget those I loved, and prepare myself for my approaching fate.
"While I was thus engaged, the surgeon. Dr. Van Voorhees, came up. He was badly wounded. His horse had been shot under him, and he had received a ball in his leg. Every muscle of his face was quivering with the agony of terror. He said to me--'Do you think they will take our lives? I am badly wounded, but I think not mortally. Perhaps we might purchase our lives by promising them a large reward. Do you think there is any chance?'
