The officers of both the Continental Army and the state militias were typically yeoman farmers with a sense of honor and status and an ideological commitment to oppose the policies of the British Crown. The enlisted men were very different. They came from the working class or minorities groups (Irish, German, African American). They were motivated to volunteer by specific contracts that promised bounty money; regular pay at good wages; food, clothing and medical care; companionship; and the promise of land ownership after the war. They were unruly and would mutiny if the contractual terms were not met. By 1780-81 threats of mutiny and actual mutinies were becoming serious. Upwards of a fourth of Washington's army were of Irish origin, many being recent arrivals and in need of work.
