The battle of Trenton: Does this first paragraph make sense? Is is good?

On December 22 of 1776, General George Washington had 4,707 of his troops fit for duty. However, the year was quickly coming to an end. More enlistments ran out, and reduced his army to fewer than 1,500 men. Winter was also around the corner and the British, who entered in the nearby winter quarters, could continue their pursuit. Luckily, George Washington was accompanied by his spies and planned immediate attack on the Brtitish soldiers. He first wanted to attack the Hessians at Bordentown, but the local militia in that area was too weak to offer support. Washington decided on a predawn attack on December 26, while the Heissan troops and officers would be drunk and tired, and hopefully suffering hangovers. Washington and his men would cross the Delaware River at McKonkey's Ferry, some 9 miles above Trenton, and surprise the Hessians from the north.
