This comprehensive contribution to the large part Irish and Irish-Americans played in the American Revolution covers genealogy, battles, fraternal organizations, and Irish friendship with George Washington. It is a refutation of Bancroft and Lodge by the historiographer of the American Irish Historical Society, with analysis of early Irish emigration to the colonies, the sympathies of the Irish with the Revolution, and the role played by the Irish in the Revolution. The appendix lists first officers, then non-commissioned officers of the American Army and Navy of the Revolution of Irish birth and descent.
