Scholarly works dealing with the Long Parliament's military finances have often necessarily relied on sampled data and exemplary evidence. This communication demonstrates that full, systematic analyses of the relevant materials in the Commonwealth Exchequer Papers have the potential to alter our understanding of these finances when certain questions are asked. Lacking a detailed calendar, this vast collection of documents is extraordinarily complex and opaque, and because of this it is very hard to deal with holistically. Nevertheless, this communication demonstrates that achieving a broad yet precise view of this vital quantitative material is sometimes possible. It will be suggested here that the army of the earl of Essex enjoyed full payment from the moment of its creation in August 1642 until the end of that October. This will be demonstrated by comparing the total payments received by the foot soldiers to a newly calculated model of their monetary needs during the period in question. Ultimately, there are many possible reasons for the army's failure to secure a decisive victory at Edgehill, but a financial crisis at the political centre was not one of them.
