AUGHRIM, or AGHRIM  , a small village in Co . Galway, Ireland, 4 M . W. by S. of Ballinasloe . It is rendered memorable by the decisive victory gained here on the 12th of July 1691 by the forces of William III. under General Ginkel, over those of James II. under the French general St Ruth, who fell in the fight . The Irish numbering 25,000, and strongly posted behind marshy ground, at first maintained a vigorous resistance; but Ginkel having penetrated their line of defence, and their general being struck down by a cannon ball at this critical moment, they were at length overcome and routed with terrible slaughter . The loss of the English did not exceed 700 killed and moo wounded; while the Irish, in their disastrous flight, lost about 7000 men, besides the whole material of the army . This defeat rendered the adherents of James in Ireland incapable of further efforts, and was speedily followed by the complete submission of the country .
