Not really. Up until that day, most were still loyal Englishmen. What they didn't want was the way-off meddling that was occuring from Parliment. The idea of war against the Crown was unthinkable by most, except for the few radicals.
True! In fact, many people were critical of Timothy Pickering, the colonel of the Essex County Militia Regiment for not attacking the British energetically enough when they were about to intercept them as a body on the way back to Boston. If Pickering had marched his men faster, and all had attacked, the British would have been wiped out. However, in his voluminous writings, he indicated that he wasn't totally certain of the efficacy or prudence of committing treason and murder of his government's troops. Pickering was known as a very conservative man, but not a Tory.
Nor were the commanders of the Plymouth County Militia willing to attack British troops. They demurred in attacking the British troops in Marshfield in April 1775....
"....British General Gage, responding to pleas from loyalists in Marshfield, stationed a company of regulars in that town. “I feel great satisfaction,” Gage wrote to the citizens of Marshfield, “in having contributed to the safety and protection of a people so eminent for their Loyalty to their King.”
The soldiers frequented taverns in Duxbury and were, historian Justin Winsor observed, generally well behaved. Although on one occasion they alarmed Duxbury citizens by gathering outside the First Parish Church, peering in the windows at the service taking place there. Despite their good behavior, the redcoats enraged people through the county simply by their proximity.
On April 19, 1775, news of the battles at Concord and Lexington quickly spread throughout New England. Colonial militia companies which had been drilling for months in anticipation of a crisis rapidly gathered in Plymouth. Under the command of Colonel Theophilus Cotton, the colonial regiment, consisting of volunteers from Plymouth, Kingston and Duxbury, headed for Marshfield to engage the British. The colonial officers held a council of war at the home of Lt. Col. Briggs Alden in Duxbury.
Nearly two days slipped by before they could agree on any action. The Americans outnumbered the British company six to one. Still, Colonel Cotton hesitated to attack—perhaps a prudent decision when faced with the gravity of outright rebellion. By 3 p.m. on April 21, British sloops had arrived off Brant Rock to take their soldiers to safety in Boston."
