 On December 10, George Washington's council determined that the Continental Army would move to winter quarters somewhere west of the Schuylkill River.The army struck camp the morning of December 11, and proceeded to march through Plymouth Meeting, across Ridge Road, and down to the river crossing at Matson's Ford (following the route of present-day Butler Pike).In preparation for the crossing, Washington ordered the Pennsylvania militia, under the command of General James Potter, to establish three advance pickets west of the river to warn of British troop movements
