The next day, Major Sherburne approached without having received any information that Butterfield had surrendered.

Within about four miles of the Cedars, he was attacked by a considerable body of Indians; and, after a sharp conflict, surrendered at discretion.
On being informed of these untoward events, Arnold, at the head of seven hundred men, marched against the enemy then at Vaudreuil, in the hope of recovering the American prisoners.
When preparing for an engagement, he received a flag, accompanied by Major Sherburne, giving him the most positive assurances that if he persisted in his design, it would be entirely out of the power of Captain Forster to prevent his savages from pursuing their horrid customs, and disencumbering themselves of their prisoners by putting every man to death.

This massacre was already threatened; and Major Sherburne confirmed the information.

Under the influence of this threat, Arnold desisted from his purpose, and consented to a cartel, by which the prisoners were delivered up to him; he agreeing, among other things, not only to deliver as many British soldiers in exchange for them, but also, that they should immediately return to their homes.] The Americans were much dissatisfied with the conduct of this gentleman.

To him they, in some degree, attributed the disasters which ruined their affairs in Canada.
