"What really weakened the royalist war-effort was the fact that the conflict had a greater impact on its territories than on those of Parliament and thus the financial machinery could not be managed properly. In particular, the war impinged closely on some of its most prosperous areas, creating a general sense of insecurity there and affecting the amount of revenue received. This, in turn, necessitated the introduction of various expedients to obtain money and essential supplies, including special levies, free quarter, and requisitioning. As final defeat stared them in the face, royalist units engaged in ever more self-destructive activity just to keep themselves alive. They started a vicious circle by robbing their own shires. Looting engendered hatred from civilians; it also rendered the countryside incapable of paying the tax upon which the soldiers' pay depended; this in turn drove the soldiers to more frantic looting. As long as the royalists had an army it could be used to coerce the population but the catastrophe of Naseby in June 1645 took away even this."
