Warrants were written authorizations to receive or deliver goods or money. The warrant books, maintained by Washington's secretaries and aides-de-camp, list warrants signed by him. Warrants could be redeemed by the army paymasters, but most often they were used like cash by recipients. Warrants, like bills of exchange and vouchers, were often heavily discounted; that is, they depreciated in value. These warrants were used by quartermasters to issue vouchers to acquire services and supplies – forage, munitions, clothing, transportation, etc. – for the use of the American military and to maintain Washington's headquarters. Dollars in these books refer to the Spanish silver dollar; ponds, shillings, and pence were Virginia currency.
