"It is said by the rebels at Roxbury that Col. Watson has given his quota to support the people"

This quote is referring to the American Revolutionary War, in which the rebels at Roxbury were battling versus the British. The quote suggests that Colonel Watson, a British officer, had actually provided resources to the people of Roxbury in order to support them. This could suggest that Watson was sympathetic to the reason for the rebels, or that he was just attempting to preserve order in the location. It is possible that Watson was attempting to win the favor of the people of Roxbury by supplying them with resources, in order to avoid them from joining the rebel cause. Additionally, it could be that Watson was trying to show his loyalty to the British crown by offering resources to the people of Roxbury. Whatever the case, it is clear that Watson was attempting to provide some type of support to the people of Roxbury, and that the rebels were aware of this.
