The Americans had inflicted heavy casualties and captured a strongly fortified position with fewer losses to themselves. The victory can be credited to excellent planning and leadership by two comparatively junior officers: Scott and Perry. When the Americans broke off the pursuit, Vincent continued his retreat to Beaver Dams, near present-day
Thorold, Ontario, where he gathered in the other British regular detachments from Fort Erie and other posts higher up the Niagara, and temporarily disbanded the militia, before falling back to
Burlington Heights near the western end of Lake Ontario. However, the American army was slow to exploit the capture of Fort George by advancing up the Niagara peninsula, and they allowed Vincent to launch a surprise attack at the
Battle of Stoney Creek, after which the Americans withdrew to Fort George. By concentrating their naval squadron against Fort George, the Americans had also left themselves vulnerable to a counter-attack on their base, and only indecisive command by Lieutenant General Sir
George Prevost allowed the Americans to fight him off at the
Battle of Sackett's Harbor. The Americans subsequently remained in a small defensive enclave around Fort George. After a disaster when a sortie against a British outpost was surrounded and forced to surrender by Native Americans at the
Battle of Beaver Dams, they remained largely inactive on this front until they abandoned Fort George in December 1813.
Ten currently active regular battalions of the United States Army (2-1 ADA, 3-4 ADA, 4-1 FA, 1-2 Inf, 2-2 Inf, 1-4 Inf, 2-4 Inf, 3-4 Inf, 1-5 Inf and 2-5 Inf) perpetuate the lineages of a number of American units (Crane's Company, 3rd Regiment of Artillery, Baker's Company, 2nd Regiment of Artillery, Leonard's Company, 1st Regiment of Artillery, and the old 6th, 13th, 14th, 20th, 21st, 22nd and 23rd Infantry Regiments) that were engaged at Fort George. ==Commemoration==
