On 21 January 1757 at the First Battle of the Snowshoes, Rogers' Rangers ambushed and captured seven Canadiens near Fort Carillon but then encountered a hundred French and Canadian militia and Ottawa Indians from the Ohio Country. Roger's forces retreated after taking casualties of 14 killed, nine wounded, and six missing or captured; the French-Indian forces were 11 killed, 27 wounded. British forces surrendered Fort William Henry in August 1757, after which the Rangers were stationed on Rogers Island near Fort Edward. This allowed them to train and operate with more freedom than the regular British forces. On 13 March 1758 at the Second Battle of the Snowshoes, Rogers' Rangers ambushed a French and Indian column and, in turn, were ambushed by enemy forces. The Rangers lost 125 men in this encounter, as well as eight men wounded, with 52 surviving. Rogers estimated 100 killed and nearly 100 wounded of the French-Indian forces; however, the French listed casualties as a total of ten Indians killed and seventeen wounded. On 7 July 1758, Rogers' Rangers took part in the Battle of Ticonderoga. In 1758, Abercromby recognized Rogers' accomplishments by promoting him to Major, with the equally famous John Stark as his second in command. Rogers now held two ranks appropriate to his double role: Captain and Major. In 1759, the tide of the war turned and the British advanced on the city of Quebec. Major General Jeffrey Amherst, the newly appointed Commander-in-Chief of British forces in North America, had a brilliant and definitive idea. He dispatched Rogers and his rangers on an expedition far behind enemy lines to the west against the Abenakis at Saint-Francis in Quebec, a staging base for Indian raids into New England. Rogers led a force of two hundred rangers from Crown Point, New York, deep into French territory to Saint-Francis. At this time, the Indians near Saint-Francis had given up their aboriginal way of life and were living in a town next to a French mission. Rogers burned the town and claimed to have killed 200; the actual number was 30 killed and 5 captured. Rogers losses were 41 killed; 7 wounded 10 captured. Following the 3 October 1759 attack and successful destruction of Saint-Francis, Rogers' force ran out of food during their retreat back through the rugged wilderness of northern Vermont. The Rangers reached a safe location along the Connecticut River at the abandoned Fort Wentworth. Rogers left them encamped, and returned a few days later with food and relief forces from Fort at Number 4, now Charlestown, New Hampshire, the nearest British town.
