Fort Ticonderoga, situated overlooking the critical waters of Lake Champlain, had been a pivotal location during the early years of the American Revolutionary War. In July 1777, the British, under General John Burgoyne, launched a major offensive against the fort. This action was part of a broader strategy to split the American colonies by gaining control of the Hudson River and its surrounding areas. Burgoyne's forces had been methodically bombarding Ticonderoga, and after several days under fire, the morale of American troops began to erode as the British artillery proved relentless and overwhelmingly effective.

The American defenders, led by General Arthur St. Clair, recognized the untenable situation as their positions became increasingly compromised. Supplies were dwindling, and reinforcements were not forthcoming. On the night of July 5th into the early hours of July 6th, St. Clair made the difficult decision to abandon the fort, executing a withdrawal strategy that would hopefully preserve his remaining forces. The tactic involved moving troops quietly to avoid detection, an effort that, despite some skirmishes, largely succeeded, allowing most of the troops to escape intact.

As dawn broke on July 6th, British forces gained entry to the now-deserted fort, realizing a significant victory in their campaign. Fort Ticonderoga was not only a military asset but also a psychological blow to American forces, illustrating the challenges they faced against a well-organized and equipped British army. The loss of Fort Ticonderoga would have immediate repercussions as it showcased the vulnerabilities of the American forces and prompted further strategic discussions among Continental commanders regarding fortifications and troop movements in the northern theater of the war.
