Following the death of Braddock, William Shirley assumed command of British forces in North America, and he laid out his plans for 1756 at a meeting in Albany in December 1755. He proposed renewing the efforts to capture Niagara, Crown Point, and Duquesne, with attacks on Fort Frontenac on the north shore of Lake Ontario and an expedition through the wilderness of the Maine district and down the Chaudière River to attack the city of Quebec. His plan, however, got bogged down by disagreements and disputes with others, including William Johnson and New York's Governor Sir Charles Hardy, and consequently gained little support. Newcastle replaced him in January 1756 with Lord Loudoun, with Major General James Abercrombie as his second in command. Neither of these men had as much campaign experience as the trio of officers whom France sent to North America. French regular army reinforcements arrived in New France in May 1756, led by Major General Louis-Joseph de Montcalm and seconded by the Chevalier de Lévis and Colonel François-Charles de Bourlamaque, all experienced veterans from the War of the Austrian Succession. On May 18, 1756, England formally declared war on France, which expanded the war into Europe and came to be known as the Seven Years' War.. What began on May 18, 1756?
