Merchants and the Military in Eighteenth-Century Britain [PDF ebook] 
British Army Contracts and Domestic Supply, 1739-1763

Investigates the contract sector of the British Army during the long eighteenth century. This book argues that this group of financiers, private merchants, businessmen and farmers represented a vital interest group which was at the nexus of the fiscal-military structure. It draws on papers from the War Office, the Treasury and the Audit Office.
