Mrs. Macvicar some time afterwards received his directions to follow him; and accompanied by their daughter, she landed at Charleston, South Carolina, in 1758, and took up her temporary residence at Albany, New York. Mr. Macvicar, having exchanged into the 55th Regiment, was sent down from head-quarters at Oswego, New York on Lake Ontario to buy stores, with leave of absence to visit his family. On his return, he took his wife and child with him to the garrison, travelling in a boat up the river. He served in the attack on Ticonderoga, 8 July 1758, when seven of his fellow officers were killed. On the declaration of peace between Great Britain and France in 1762, the 55th Regiment was ordered to New York, previous to embarkation for England.
