Upon the close of the war, the Rangers were disbanded, the officers being placed on the half-pay list. Young Simcoe had meanwhile been promoted to the rank of Lieutenant-Colonel. During the progress of hostilities he had conceived an intense dislike to the colonists and their political principles, and the termination of the war caused no change in his sentiments toward them. This aversion accompanied him through life, and as we shall presently see, was destined to materially affect his subsequent career. Meanwhile, he returned to England with his constitution much impaired by the hard service he had undergone. Rest and regular habits, however, soon enabled him to recover, in a great measure, his wonted vigour. We next hear of him as a suitor to Miss Gwillim, a near relative of Admiral Graves, Commander of the British fleet during the early part of the Revolutionary War. The courtship soon terminated in marriage; and not long afterwards the ambitious young soldier was elected as member of the British House of Commons for the constituency of St. Maw's, Cornwall. The latter event took place in 1790. During the following session, Mr. Pitt's Bill for the division of the Province of Quebec into the two Provinces of Upper and Lower Canada came up for discussion. The member for St. Maw's was a vehement supporter of the measure, and upon it receiving the royal assent the appointment of Lieutenant-Governor of the new Province of Upper Canada was conferred upon him. He sailed from London on the 1st of May, 1792, accompanied by a staff of officials to assist him in conducting the administration of his Government. His wife, with her little son, accompanied him into his voluntary exile, and her maiden name is still perpetuated in this Province in the names of three townships bordering on Lake Simcoe, called respectively North, East, and West Gwillimbury. The party arrived in Upper Canada on the 8th of June, and after a brief stay at Kingston took up their abode at Newark, near the mouth of the Niagara River.
