In military terms, by the end of 1644 the Royalists had recovered from the disaster at Marston Moor; of greater concern was their ability to finance the war. Unlike Parliament, which could levy taxes on imports and exports through London and other commercial centres, the Royalists simply took supplies from the areas they controlled. This led to the creation of Clubmen, or local self-defence associations; they opposed confiscations by either party, but were a bigger issue in Royalist areas like Cornwall and Hertfordshire.
