A few days after these incidents a body of "patriots" under the leadership of James Moreau crossed the Niagara frontier in order to free Upper Canada. Moreau, who is called Morrow in the Canadian records, issued a proclamation which called upon the Canadians to come to his assistance and proclaimed that this was the hour of their redemption. The answer of the "oppressed Canadians" was the engagement fought at the Short Hills on June 21st when the "patriots" were defeated by the Canadian militia. Moreau fled with a price on his head but was captured, tried and condemned to death. The Executive Council on July 26th refused to reprieve him since he was considered a proper case for capital punishment under an Act of the Parliament of Upper Canada passed the previous session in order "to protect the Inhabitants of this Province against lawless aggressions from Subjects of Foreign Countries at Peace with Her Majesty." Moreau was accordingly executed at Niagara on July 30th. If Sir George Arthur had had his way there would have been more executions, but Lord Durham intervened. The next serious outbreak on the frontier was the attack of von Schoultz near Prescott on November 11th. The invaders seized a point of land on which a stone windmill had been built and fortified the place. An engagement ensued and the invaders were driven back to shelter within the windmill. On the 14th of November British reinforcements, including artillery, arrived, and two days later an attack was made at the distance of only 400 yards. The garrison of the windmill then surrendered and nearly 160 prisoners were taken.[29] Von Schoultz and nine others were executed in Kingston. Von Schoultz was defended by Sir John A. Macdonald, then a young barrister just beginning his profession, but there was little that could be said in his defence. The last movement against Upper Canada took place on December 4th, when an attack was made on Windsor. This affair is thus described in the District General Orders of December 10th, dated at Toronto:[30] "A large body of pirates and brigands, belonging to the hostile combination in the neighbouring country which has of late so much disturbed the peace of this province, after assembling in the neighbourhood of Detroit, and showing themselves at different points in the vicinity, at length had the hardihood to effect a landing near Windsor, about three miles from Sandwich, on the morning of the 4th instant, where they commenced their work of destruction by burning a steam-boat called the "Thames," and a house used as a barrack, making prisoners a small but gallant party of militia quartered therein, who, in defending themselves against the attacking banditti shot their leader and eventually effected their escape."
