He searched the baggage belonging to the evicted settlers and scrutinized their books and papers. 'Those who play at bowls,' remarked 'Justice' M'Leod, 'must expect to meet with rubbers.' Pritchard was told to write his version of the recent transactions at 'the Forks,' and did so; but his account did not please M'Leod. 'You have drawn up a pretty paper,' he grumbled; 'you had better take care of yourself, or you will get into a scrape.'

Michael Heden also was examined as to his knowledge of the matter. When M'Leod heard the answers of Heden he was even more wrathful.

'They are all lies,' he declared with emphasis.

The result of M'Leod's judicial procedure was that five of the party were detained and placed under arrest. The others were allowed to proceed on their way. John Bourke was charged with felony, and Michael Heden and Patrick Corcoran were served with subpoenas to give evidence for the crown against him, on September 1, at Montreal. John Pritchard and Daniel M'Kay were among the five detained, presumably as crown witnesses. After some delay—M'Leod had to visit Fort Douglas and the neighbourhood—the prisoners were sent on the long journey to Fort William on Lake Superior. Bourke was at once stripped of his valuables and placed in irons, regardless of the fact that his wound was causing him intense suffering. During the whole of the journey he was compelled to lie manacled on a pile of baggage in one of the canoes.

Fort Douglas on the Red River was still standing, but the character of its occupants had changed radically. At first Cuthbert Grant took command, but he soon made way for Alexander Macdonell, who reached Fort Douglas shortly after the affair at Seven Oaks. When Archibald Norman M'Leod appeared, he was the senior officer in authority, and he took up his residence in the apartments of the late Governor Semple. One day M'Leod and some followers rode over to an encampment of Crees and Saulteaux near the ruins of Fort Gibraltar. Here M'Leod collected and harangued the Indians. He upbraided them for their failure to interfere when Duncan Cameron had been forcibly removed to Hudson Bay, and he spoke harshly of their sympathy for the colonists when the Nor'westers had found it necessary to drive them away. Peguis, chief of the Saulteaux and the leading figure in the Indian camp, listened attentively, but remained stolidly taciturn. On the evening of the same day the Nor'westers returned to Fort Douglas and indulged in some of their wildest revelries. The Bois Brûlés stripped themselves naked and celebrated their recent triumph in a wild and savage orgy, while their more staid companions looked on with approval.

According to the testimony of Augustin Lavigne, M'Leod during his stay at Fort Douglas publicly made the following promise to an assembly of Bois Brûlés: 'My kinsmen, my comrades, who have helped us in the time of need; I have brought clothing for you I expected to have found about forty of you here with Mr Macdonell, but there are more of you. I have forty suits of clothing. Those who are most in need of them may have these, and on the arrival of the canoes in autumn, the rest of you shall be clothed likewise.'
