[Sidenote: 1770] Colonel John Hale, having been appointed Governor of Limerick, was succeeded in the colonelcy of the regiment by Colonel George Preston, from the lieut.-colonelcy of the Scots Greys, by commission dated the 2nd of November, 1770. [Sidenote: 1775] While the SEVENTEENTH were in Ireland, they had the reputation of being a well-disciplined and an efficient corps, and on the breaking out of hostilities, in 1775, between Great Britain and her North American colonies, the high character of the regiment occasioned it to be the first cavalry corps selected to proceed across the Atlantic. It embarked from Ireland towards the end of March, and landed at Boston on the 24th of May. Soon after the regiment arrived at Boston, the American troops attempted to establish themselves on _Bunker's Hill_, but were driven from thence, after a sharp engagement, on the 17th of June. During the action a party of the SEVENTEENTH volunteered to proceed dismounted with the reinforcement sent from Boston to support the troops engaged. Notwithstanding their defeat at Bunker's Hill, the American troops crowded round Boston in such numbers, and constructed such extensive works, that the British were kept in a state of blockade on the land side, and were so distressed for fresh provisions, that live cattle, vegetables, and even fuel, were sent from England for their use. These supplies proved insufficient, and the troops endured much distress. In the mean time the Americans, possessing every necessary article in abundance, began to act with vigour, raising batteries and opening a cannonade on the place. [Sidenote: 1776]
