the five regiments averaged around 300 men each. Mifflin's brigade crossed the Delaware River to Burlington, New Jersey on 28 December. By 1 January 1777, Mifflin moved his troops to Bordentown, New Jersey. He joined the main army the next day in time to be present at the Battle of the Assunpink Creek. Mifflin was at George Washington's council of war that evening. Before the Battle of Princeton on 3 January 1777, the Pennsylvanians made the second night march in a row with very little sleep and the soldiers were exhausted. The order of march for John Sullivan's division was a vanguard under Isaac Sherman followed by the brigades of Arthur St. Clair and Mifflin. While Sullivan's column swung to the right, the troops under Nathanael Greene turned to the left, led by 350 men under Hugh Mercer. Charles Mawhood's British 17th Foot and 55th Foot immediately confronted Greene's column. After a firefight, the British charged and routed the American vanguard, mortally wounding Mercer. Mawhood's soldiers advanced toward the Thomas Clark House and hill but were halted by cannon fire from Joseph Moulder's artillery company. As the British attack stalled, Washington patched together a line from the brigades of John Cadwalader, Daniel Hitchcock, Edward Hand, and Mifflin. After exchanging volleys with the British, the Americans finally advanced. Mawhood's outnumbered force put up a spirited resistance but his soldiers finally broke ranks and fled. Philadelphia campaign On 22 May 1777, Washington placed the 11th Regiment in the 2nd Pennsylvania Brigade. The other units in the 2nd Brigade were 4th, 5th, and 8th Pennsylvania Regiments. Major General Benjamin Lincoln led the Pennsylvania division, but he was later sent on detached duty and the 1st Pennsylvania Brigade's commander Brigadier General Anthony Wayne led the division in his absence. Brigadier General John Philip De Haas was named commander of the 2nd Pennsylvania Brigade, but he never joined his brigade for reasons that remain unclear to this day. In De Haas' absence, Humpton led the brigade at the Battle of Brandywine on 11 September 1777. Wayne's 2,000-man division deployed in a single battleline east of Chadds Ford on Brandywine Creek. The 1st Brigade under temporary commander Thomas Hartley formed on the right while the 2nd Brigade held the left. The 5th Pennsylvania held the extreme left flank, while to its right, in order, were the 11th, 8th, and 4th Pennsylvania Regiments. Wilhelm von Knyphausen's British
