On December 1, 1836 Colonel Foster arrived at the site with 430 men to rebuild the fort and bridge that had been destroyed months earlier.

The armament and supplies at Fort Foster consisted as follows: A six-pounder gun and a twelve pounder howitzer with at least 100 rounds of ammunition for each.

Fort Foster continued to be garrisoned as a supply post by Navy Lieutenant Thomas J. Leib, two midshipmen and about 50 sailors from USS Concord.

The 3rd and 4th Artillery Regiments provided Lt. Leib with 20 artillerymen to man the six-pound iron gun and twelve-pound howitzer to assist defending the fortification and bridge.

During the summer, the fort was abandoned due to reductions in hostilities and an increase of disease among its forces, aka, the sickly season.
