During the War for Independence, Fort Ticonderoga’s guns, sited critically between Lakes Champlain and George, dominated north-south communications in upstate New York that were vital to both the British and American war efforts. In the public mind Ticonderoga was the “American Gibraltar” or the “Key to the Continent,” and patriots considered holding the fort essential to the success of the Revolutionary cause. Ticonderoga was a primary target in British Lieutenant General John Burgoyne’s 1777 campaign to crush American resistance in the north and end the rebellion in a decisive stroke. American efforts to defend the fort in June against overwhelming odds entailed political and military intrigue, bungling, heroism, and ultimately a narrow escape for the Continental and provincial forces under Major General Arthur St. Clair. The loss of Ticonderoga stunned patriot morale and ignited one of the greatest political firestorms of the war. But the fortunes of war turned. Two months later, the rebels mounted a sensational—if little known—counter-attack on Ticonderoga that had major implications for Burgoyne’s eventual defeat at Saratoga in October. Yet Saratoga brought no peace, and Ticonderoga would be central to additional military and political maneuverings—many of them known only to specialist historians—that would keep the region on edge until the end of the war in 1783.  Based on new archival research and taking advantage of the latest scholarship,  Fort Ticonderoga, The Last Campaigns: The War in the North, 1777-1783  by distinguished historian Mark Edward Lender highlights the strategic importance of the fort as British, American, and regional forces (including those of an independent Vermont Republic) fought for control of the northern front at a critical point in the war. The book tells the Ticonderoga story in all of its complexity and drama, correcting misconceptions embedded in many previous accounts, and sheds vital new light on this key chapter in America’s struggle for independence.
