DELAWARE REGIMENT or BATTALION In December 1775 Congress resolved that a "battalion" should be raised from the lower three counties of Pennsylvania. These three counties are what is now Delaware. Delaware was not yet a completely separate state and was still part of the colony of Pennsylvania.
The "battalion" was also called a regiment.
On 21 January 1776 the list of officers was completed. John Haslet was appointed Colonel. Haslet's regiment was judged among the very best combat units in Washington's command. Haslet's regiment was the only unit of Continental regulars recruited in Delaware.
James Adair who m. Truesdale may have been in a Delaware Regiment (Capt. Allen McLane).
