Obstreperous to the point that Washington began to wish they had never come.

From 1776 by David McCulough. Page 38.

One Virginia company, led by Captain Daniel Morgan, had marched on a “bee-line” for Boston, covering six hundred miles in three weeks, or an average of thirty miles a day in the heat of summer.

Mostly backwoodsmen of Scotch-Irish descent, they wore long, fringed hunting shirts, “rifle shirts” of homespun linen, in colors ranging from undyed tan and gray to shades of brown and even black, these tied at the waist with belts carrying tomahawks. At a review they demonstrated how, with their long-barreled rifles, a frontier weapon made in Pennsylvania and largely unknown in New England, they could hit a mark seven inches in diameter at a distance of 250 yards, while the ordinary musket was accurate at only 100 yards or so. It was “rifling”—spiraled grooves inside the long barrel—that increased the accuracy, and the new men began firing at British sentries with deadly effect, until the British caught on and kept their heads down or stayed out of range.

Welcome as they were at first, the riflemen soon proved even more indifferent to discipline than the New Englanders, and obstreperous to the point that Washington began to wish they had never come.
