Capture of Fort Ticonderoga
The May 10, 1775 capture of Fort Ticonderoga was a small action with disproportionate strategic value. The rebels gained a key northern post, material, and a foothold on the route toward Canada, while the fort’s artillery later became part of the Boston siege story.

Side-by-Side Analytical Matrix
| Dimension | Battle of Harlem Heights | Capture of Fort Ticonderoga |
|---|---|---|
| Result | American victory | American victory |
| Tactical outcome | American forces checked and drove back British light troops in fighting in upper Manhattan. | A small rebel force associated with Ethan Allen, Benedict Arnold and the Green Mountain Boys surprised the lightly held British post and took Fort Ticonderoga with little fighting. |
| Strategic effect | The limited victory improved morale immediately after the disasters on Long Island and at Kip’s Bay but did not reverse British control of lower Manhattan. | The capture opened a strategically important Lake Champlain position to the revolutionaries and gave them access to artillery and stores; guns from the northern forts later contributed to the artillery concentration around Boston. |
| Terrain problem | The fighting occurred across the heights of northern Manhattan, where broken ground and elevated positions shaped movement. | Ticonderoga sat at a narrows controlling movement between Lake George and Lake Champlain. The strategic value of the site was far larger than the number of troops inside the fort on May 10. |
| Intelligence problem | The engagement developed from probing and pursuit rather than a preplanned full-scale battle; both sides committed additional troops as the action grew. | The attackers exploited surprise and local knowledge. The British garrison did not face a formal siege; the action turned on reaching and entering the fort before resistance could be organized. |
| Turning point | The American counter-movement threatened the British flank and helped force the British troops back toward their lines. | The decisive moment was penetration of the post itself. Once the small garrison was surprised inside a fort not prepared for a full defense, the contest was effectively settled. |
