The New Model Army was formed as a result of dissatisfaction among Parliamentarians with the conduct of the Civil War in 1644. Although the Parliamentarians had a clear advantage in financial resources and manpower over the Royalists, most of their forces were raised by local associations of counties, and could rarely be used far from their homes. As early as 2 July of that year, Sir William Waller discovered that his London-based units were refusing to campaign further afield, and wrote, "An army compounded of these men will never go through with your service, and till you have an army merely your own that you may command, it is in a manner impossible to do anything of importance".
