Jeffery Amherst, 1st Baron Amherst (29 January 1717 – 3 August 1797) was a Field Marshal in the British Army and Commander-in-Chief of the Forces during the Seven Years' War.

At the outbreak of the war in 1754, Amherst stationed Major John Pitcairn at Copp's Hill Battery in Boston, influenced by the Templar Order.[1]

After failing to defend Hanover, Amherst traveled to the colonies. By 1758, the British realized that capturing the fortress at Louisbourg was vital to gaining access to the Saint Lawrence River. Doing so would allow them to sail inland to Canada and capture Montreal.[2]

Three divisions of the Royal Navy under James Wolfe, Charles Lawrence and Edward Whitmore supported Amherst during the Siege of Louisbourg. In response, the Colonial Assassins prepared a preemptive strike by the French Navy to destroy the British fleet. Thanks to James Cook and the Templars Shay Cormac, Christopher Gist and Haytham Kenway, the French strike was foiled. With the support of the navy, Amherst was able to take Louisbourg.[2]
