Tecumseh felt that the great purpose of his life was about to fail. He had been champion not only of the rights of the Indians, but of their very existence as a nation. Dear to his heart was the freedom of his people, and to achieve this had been his sole ambition. All the powers with which he had been endowed—his superb physical strength, his keen intellect, his powerful oratory—had been used to this one end. But now the cause for which he had fought so heroically in the face of frequent disaster seemed about to be overthrown by Procter's weakness and irresolution. Tecumseh was born to command, and his proud spirit, naturally intolerant of control, chafed at following the dictates of a leader who had deceived him. The Indians had lost faith in Procter. There were daily desertions, and Tecumseh bitterly meditated following the example of other chiefs. But his courageous spirit revolted at the thought of retreat: to fly before the enemy without striking a blow seemed to him the action not of warriors but of cowards.

Procter pointed out that the fort, which had been dismantled to equip the Detroit, was open to attack from the river; that the hospital was filled with sick soldiers; and that starvation stared the British in the face. But the argument which weighed most with Tecumseh was that they would be able to find along the river Thames a place much better suited for battle. And at last the Indian leader reconciled his mind to the thought of retreat.

The troops were soon busily engaged in loading the baggage. Part was stowed in boats to be sent inland by way of the Detroit river, Lake St Clair, and the Thames; the remainder was placed in heavy wagons to be taken overland. The women and children, among whom were the general's wife and his sick daughter, were sent on ahead, the squaws trudging along bearing their papooses on their backs. The troops set fire to the shipyards, fortifications, and public buildings on September 24, and marched out leaving Amherstburg a mass of flames. Tecumseh seemed sad and oppressed; and as he gazed at the rolling clouds of smoke he said to Blue Jacket: 'We are now going to follow the British, and I feel well assured we shall never return.'

Procter halted at Sandwich, where he was joined by the garrison of Detroit, now also abandoned by the British, its fortifications and public buildings having been destroyed. On the morning of the 27th the column moved out of Sandwich. The lumbering wagons, encumbered with much heavy and unnecessary baggage, made slow progress. Procter's energy had vanished, and he displayed none of the forethought that a commander should have in the performance of his duty. He took no precaution to guard the supply-boats; his men were indifferently fed, and no care was taken for their safety. Even the bridges, which should have been cut down to hamper the progress of the enemy in pursuit, were left standing.

Three days after Procter's flight from Amherstburg Harrison landed below the town from Perry's vessels an army about five thousand strong. Finding Fort Malden a smoking ruin, and no enemy there, he pressed on to Sandwich, with his bands playing Yankee Doodle, and encamped. Two days later he was joined by Colonel Johnson with fifteen hundred cavalry, and on the same day (September 29) a flotilla under Perry sailed up the river and stood off Detroit. After taking possession of Detroit, Harrison resolved to hasten in pursuit of the British. On October 2 he left Sandwich with four thousand men, sending his baggage by water under the protection of three gunboats which Perry had provided. Thus unencumbered, his troops marched rapidly. On the morning of the 3rd they overtook and captured a small cavalry picket of the British; and keeping in motion throughout the day, they encamped that night not far below the place known as Dolsen's, on the south side of the Thames river, about six miles below Chatham.

The main body of the British had left Dolsen's just a day in advance of the enemy, having travelled only forty-five miles in five days. All along the route Tecumseh had persistently urged that a stand should be made. Procter had promised that this should be done, first at one place, then at another; but each time he had made some excuse. At length, when they came to the site of the present city of Chatham, where McGregor's Creek falls into the Thames, Tecumseh pointed out to Procter the natural advantages of the ground and appealed to him to prepare for battle. The general approved of making a stand at this point, and declared that the British would either defeat Harrison here or leave their bones on the field of conflict. After the leaders had completed their survey of the proposed battle-ground, Tecumseh gazed musingly at the swiftly flowing waters. 'When I look at those two streams,' he said, 'they remind me of the Wabash and the Tippecanoe.' A gentler light shone in the warrior's eyes; his thoughts were far away among the scenes of his Indian village—the village that he had hoped to make the centre of a great confederacy of red men.

Meanwhile the main body of the British troops were at Dolsen's, where they had arrived on the 1st of October. Leaving his troops at their camp, and Tecumseh and his Indians at Chatham, Procter set out with a guard to escort his wife and daughter to Moraviantown, a village of the Delaware Indians, twenty odd miles farther up the river. He was still absent on October 3, when scouts returned with news of the capture of the cavalry picket. Procter had left no orders; and Warburton, the officer in command, was at a loss what action to take. After consulting with Tecumseh, who had come down from Chatham, he ordered a retreat for two miles up the river; there the troops formed up, fully expecting attack. But as the enemy failed to appear, they proceeded to Chatham. Tecumseh desired the troops to halt and encamp with his Indians on the opposite side of the river. Warburton, however, desired to continue the retreat. But Tecumseh would not yield, and Warburton ordered his men across the stream, where the entire force camped for the night. Next morning, before the troops had breakfasted, scouts rushed into the camp bringing word of the rapid advance of the enemy. Immediately Warburton ordered his men to march, not allowing them time even to take food. About six miles up from Chatham Procter joined the army and took command. The retreat continued until nightfall, when the troops encamped about five miles below Moraviantown, on the north bank of the Thames, where the village of Thamesville now stands.

But Tecumseh and his band had not accompanied the retreating party; and when Harrison reached McGregor's Creek at Chatham, he found his progress checked. The bridge there had been destroyed, and Tecumseh with his warriors disputed the passage. Harrison, thinking he was opposed by the whole British force, marshalled his army and brought up his artillery. After a slight skirmish, in which Tecumseh was wounded in the arm, the Indians were forced to fall back. A second bridge was similarly contested, with a like result. Then Tecumseh and his Indians retreated and joined Procter's forces near Moraviantown, while the Americans pushed eagerly forward. Drifting down-stream were seen several British boats, which had been deserted by their occupants and set on fire.

The morning of the 5th found Harrison near Arnold's Mills, where he overtook and captured two gunboats and some bateaux laden with supplies and ammunition. A few of the occupants escaped and fled overland towards the British camp. Harrison's men then crossed the Thames, some of them in boats and canoes and others on horseback. By noon the entire American army had reached the opposite shore, where, farther up, the British were bivouacked, only a short march distant.

On the morning of the same day, while the soldiers were waiting for their rations to be meted out, the fugitives from Arnold's Mills arrived at Procter's camp and informed him of the capture of the gunboats and of Harrison's near approach. Tecumseh was sitting on a moss-covered log, smoking and discussing the situation with Shaubena and a few of his chief warriors, when a messenger summoned the Indian leader to the general's headquarters. He returned after a short absence, with clouded brow and thoughtful mien, and silently resumed his pipe. One of the chiefs finally asked, 'Father, what are we to do? shall we fight the Americans?' 'Yes, my son,' slowly replied Tecumseh. 'We will be in their smoke before sunset.'
