Partly as a result of this indecision, and the fact that it would be isolated from its supply lines if Howe moved north, the garrisons at Fort Ticonderoga and elsewhere in the Mohawk and Hudson valleys were not significantly increased. Schuyler took the measure in April 1777 of sending a large regiment under Colonel Peter Gansevoort to rehabilitate Fort Stanwix in the upper Mohawk valley as a step in defending against British movements in that area. Washington also ordered four regiments to be held at Peekskill, New York that could be directed either to the north or the south in response to British movements.
