About 75 years before the Army started to build a new training camp near West Point, Kentucky that would be named in honor of Henry Knox, the Army began building a massive fortification on the Penobscot River in Maine that bore the name Fort Knox. Knox was the Continental Army’s chief of artillery during the Revolutionary War whose retirement home Montpelier in Thomaston, Maine I described in an earlier post.

Control of the Penobscot River, almost directly west of the southern tip of Nova Scotia, made it important to both the British and the Americans. It was the scene for the fledgling break-away colonies first major naval defeat in 1779, and the British regained control during the War of 1812. Thus, it was a logical location to place one of about 40 forts started as part of the Third System of defense in 1844. Construction on Fort Knox continued for almost 25 years, but as the Civil War drew to a close, concerns about a sea-born invasion waned and the fort’s barracks were never completed.

Fort Knox is a massive granite-walled fortification with mounts for 135 cannon, some in batteries and some in casemates. A diagram showing the layout of the fort can be found here.

The exterior granite walls are indicative of the fine quality of workmanship
The largest number of troops ever stationed at the fort was 575 when a Connecticut regiment lived outside the walls in tents for a month during the Spanish-American War. During the Civil War 20 to 54 troops were garrisoned at the fort. For the best part of fifty years, after construction stopped in 1869, a non-commissioned officer served as the sole guardian of the fort.

Only 74 cannon were ever placed on the 135 mounts
This will probably be my last post about my trip to Maine, so let me close with one of those quintessential Maine seaport views. This one was taken from the roof of the fort’s casemates.
