About a third of the Colonists support England, a third were for Independence, and a third didn't give shit who who won as long as they were left alone to get on with the sowing, harvesting and other daily tasks. This according to John Adams, who was there and ought to have known.

I find most revolutions are that way, except that the "don't give a shit" portion is usually larger than 1/3.

One immediate effect of the Colonies losing the War would have been at least a hundred bodies swinging in the wind -- assuming that they were left unquartered.
