A month after Loftus joined
Colonel Harrison's Regiment of Foot, he was promoted to
lieutenant, likely as part of the
Irish establishment. Having served in his father's regiment for twenty years, Loftus transferred to the
22nd Regiment of Foot in October 1760, and was promoted to the rank of
Major. The regiment took part in the capture of
Martinique and the
Siege of Havana in 1762, where Loftus was commended for his leadership of a force of six hundred and two rank and file. The regiment moved in 1763 to
West Florida, which at the time encompassed all territory between the
Mississippi and
Apalachicola Rivers with its capital at
Pensacola, which is where Loftus was stationed.
Loftus Heights In 1763, Britain signed a
peace treaty with France, ending the seven years'
French and Indian War. All French
Illinois country east of the Mississippi were ceded to British control, an area so vast that
“England found herself in possession of more territory at the close of the French and Indian war than her king and ministry could well govern”. The first expeditionary force to exert control over the territory was assigned to Loftus, who was charged with taking possession of the
fortress of Chartres, the administrative centre for the region. The plan had been conceived by Colonel
Robertson and involved mounting a waterborne expedition to travel the nine-hundred-mile stretch of the Mississippi from New Orleans and taking possession of Fort Chartres, a journey that was expected to take two to four months, assuming the full cooperation of the French. Colonel Robertson had arranged for boats and equipment to be procured in New Orleans but had been unable to recruit a guide for expedition. Despite Loftus applying severe discipline amongst his men, the French Governor reported twenty desertions before the expedition had started. Loftus picked up the boats and provisions and set off heavily laden on February the 27th. The Mississippi river was in full flow, creating strong currents, which, when combined with adverse winds, made progress both laborious and slow. Disease began to take hold, resulting in one death and frequent desertions. After three weeks and two hundred and forty miles, the flotilla was attacked by
Tonica Indians at
Roche Davion. Loftus abandoned the expedition, having lost around a quarter of his men, mostly through desertions. The failure of the expedition arguably encouraged the Indians to resist British rule, resulting in
Pontiac’s War. ==Political career==
