On June 15, the British began to withdraw from Philadelphia, crossing the River Delaware into New Jersey. The last troops crossed three days later, and the army consolidated around Haddonfield. Clinton, who had not yet decided on the exact route to New York approximately away, divided his army into two divisions and set out for Allentown, some to the northeast. He accompanied the first division, which comprised some 10,000 troops under the command of Lieutenant General Charles Lord Cornwallis. The second division, commanded by Lieutenant General Wilhelm von Knyphausen, comprised just over 9,000 personnel, of which over 7,500 were combatants. This division contained the bulk of the slow-moving heavy transport of the 1,500-wagon baggage train.
