Historic Fort Klock is a fortified farm homestead in New York's Mohawk Valley.

Fort Klock: 1750, St Johnsville, Mongomery County. An L-shaped, two and half story stone house with loopholes built by Johannes Klock. Located on Route 5, on the north bank of the Mohawk, one mile east of St Johnsville center and 3/4 miles south of Fort Hess. Fort Klock was restored and is open as a museum. Battle of Klock's Field, October 19, 1780, was just east of the Fort.

Fort Klock was built in 1750 by Johannes Klock, a Palatine German. Johannes Klock did have a son Jacob, but he was not the commanding officer of the Tryon County Militia. It was Johannes's brother who was Col. Jacob Klock. There were three Fort Klock's in the Mohawk Valley during the Revolutionary War and history books get them mixed up. Col. Jacob Klock lived about a mile west of Johannes Klock's home which is known as Fort Klock, although Col. Jacob must have visited it many times, he did not live here.

His home was also known as Fort Klock during the Rev. War. The other Fort Klock was located east of Johannes's home. That was also a Fort House that belonged to Christian Klock, it was called Fort House after the builder and to distingush it from the other Fort Klock's in the area.

Three years after Oriskany, Sir John Johnson and Joseph Brant led another one of their devastating raids on the Mohawk Valley in October of 1780. This one is referred to as the Great Raid of 1780 because of the destruction they caused and the lives lost.

While area residents sought the shelter of Fort Klock, Johnson and Brant setup a line of battle between Fort Klock and St. Johnsville.

The American forces under the command of General Robert Van Rensselaer charged the enemy position and after a short skirmish, the raiders fled in an utter rout. The American forces began to pursue the retreating enemy, but after Van Rensselaer called back his forces, most of the raiders escaped westward.

The Battle of Klock’s Field was the end of the Great Raid of 1780.

Reenactors portray some of the war dead from the battle to take the homestead fort.  In the background can be seen women grieving for their husbands and fathers.
