France and Great Britain spent 1.3 billion livres and 250 million pounds, respectively . The United States spent $400 million in wages for its troops . Spain increased its military spending from 454 million reales in 1778 to over 700 million reales in 1779 . </P> <P> The economic warfare between Great Britain and the colonists began well before the colonies declared their independence in 1776 . Regulations from the crown were met with fierce opposition from the colonists . After lobbies and petitions proved ineffective, the colonists turned to boycotting imported English goods . Boycotting proved to be successful in crippling British trade . After the first colonial boycott in 1765, Parliament overturned the Sugar and Stamp Acts, and after a second boycott in 1768 Parliament overturned all of the Townshend duties except for the tax on tea . The colonists persisted, and the American boycott on tea ultimately culminated in the Boston Tea Party of 1773 . Despite the Revolution's widespread association with the colonists' aversion to higher taxes, it has been claimed that the colonists actually paid far less tax compared to their British counterparts . </P>
