A masterclass in military incompetence: how 16,000 men lost to 4,000
In short: In 1758, the British launched a massive invasion of New France with an army so large it was the biggest ever deployed in North America at that time. Yet, through a series of catastrophic errors in judgment, they were routed by a much smaller French force in one of history's bloodiest tactical failures.
On 8 July 1758, combat occurred at Carillon (or Ticonderoga). It serves as a textbook example of tactical incompetence. Despite having a massive numerical advantage, the British suffered over 3,000 casualties, while French losses were only about 400.
The failure was rooted in Abercrombie's leadership and flawed intelligence. Historian Lawrence Henry Gipson described the campaign as involving a greater number of errors of judgment than any other on American soil. Confident of a quick victory, Abercrombie ignored viable options like flanking the French breastworks or laying siege to the fort. Instead, he relied on a flawed report from a young engineer and opted for a direct frontal assault on thoroughly entrenched positions without using field artillery—a lack that left his troops completely vulnerable.
The geography of the site played a role in the tragedy. Positioned for strategic advantage, the stronghold lay where Canadian French troops met British units heading north along the Hudson. While Montcalm was aware of the fort's geographic defects, such as Mount Defiance (Rattlesnake Hill), which provided an excellent firing position for cannons, he was forced to defend it with limited time and supplies. The resulting battle gave the fort a reputation for impregnability that influenced military operations for decades, even though the British eventually captured the abandoned site the following year.
The strategic context was equally complex. William Pitt had shifted British policy toward an offensive strategy in North America, but political considerations led to the appointment of the 'relatively undistinguished' Abercrombie over more skilled tacticians. Meanwhile, French forces were struggling with a poor harvest and a lack of support from King Louis XV, who was unwilling to risk naval movements against the dominant British Royal Navy.
