[2] According to Trussell, on "October 5, 1776, the Pennsylvania Council of Safety took the first step toward consolidating the remnants of Miles's Regiment and Atlee's Battalion by asking Lieutenant Colonel Brodhead to supply lists of those of his officers who desired to join the Continental Army and those who wanted to remain in the service of the State."

Following the addition of an eleventh company "to guard powder mills," the regiment's transfer to the Continental Army was finalized on June 10, 1777.

On 17 June 1777, Walter Stewart became the unit's commander and led it at the Battle of Brandywine where it fought with George Weedon's 2nd Virginia Brigade.

John George Hoffner (1735–1799), who had joined Miles's regiment as a sergeant in May 1776 and had been promoted to ensign the following fall, was appointed first lieutenant with the 13th Pennsylvania in March 1777, and then commissioned as a captain at the end of that same year.

Sunbury resident Jacob Snider (c.1755–1791), was appointed as a sergeant in Miles's regiment in March 1776 and then later made an ensign before becoming a captain in the 13th Pennsylvania on April 18, 1777.
