Bellum Battle Comparator
Compare two engagements without flattening incompatible historical numbers. Bellum contrasts outcome, terrain, tactical sequence, command decisions, documented formations, primary-source depth and evidence quality while keeping each source definition intact.
December 31, 1775 · Quebec
The failed American assault on Quebec on December 31, 1775 was the climax of the invasion of Canada. It combined severe operational time pressure with difficult urban terrain, divided assault columns and a determined garrison under Guy Carleton.
May 10, 1775 · New York
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.
| Dimension | Battle of Quebec | Capture of Fort Ticonderoga |
|---|---|---|
| Result | British victory | American victory |
| Tactical outcome | The American assault on Quebec failed in a snowstorm. Richard Montgomery was killed, Benedict Arnold was wounded, and a large number of attackers were captured after fighting in the lower town approaches. | 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 defeat ended the best American chance to seize Quebec City. The besiegers remained outside the city for months, but British reinforcements in spring 1776 forced the Continental army into retreat. | 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 | Quebec’s cliffs, walls, narrow lower-town streets and restricted approaches forced the Americans into separated columns. The city’s fortifications and urban bottlenecks made coordination difficult. | 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 Americans knew time was working against them because enlistments were expiring. That pressure encouraged a high-risk night assault even though the defenders understood the likely approaches and the weather complicated communication. | 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 | Montgomery’s column was stopped and its commander killed, while Arnold’s thrust became trapped in the lower town. With the attacks separated and leaders disabled, the defenders could isolate and capture surviving attackers. | 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. |
