With orders to relocate to New York City, the British army spends two weeks establishing a post at Cooper’s Ferry, near Camden, across the Delaware River from Philadelphia. On June 1, 1778, the British begin moving wagons and provisions across the river. Further upriver, George Washington (pictured) is making similar preparations to move his army across the Delaware so as to engage the British. This will ultimately happen on June 28, at the Battle of Monmouth.
