UPon Friday the 10th instant , our Army moved from Athlone , and Encamped that night at Killcashell , 7 Miles nearer to the Enemy , whence the General went to view the Pass at Ballynasloe , and perceiving the Parties the Enemy had abroad to withdraw upon our advancing , he went on to Leagh , a large Mile beyond Ballynasloe .

Upon Saturday the 11th , about 4 in the morning , we decamped , & marched to Ballynasloe , and encamped all long on the Roscommon side of the River Suck ; The General went to the Hills of Knockdunloe in the County of Galway , half a mile distant from our Camp , whence he could perceive the Enemies Out-Guards upon the Hills of Corbally , who upon our approach retreated to the Isker of Liscapull , two miles beyond Ballynasloe , upon which he went forward to the Hills of Corbally , whence he could take a view of the Enemies Camp , which was formed beyond Aghrim , about three miles beyond Ballynasloe , and extended it self from the Church of Killcommodan on their right , to a place called Gurtnapory on the left , above 2 miles in length , a Mapp of which being drawn , it presented it self thus : On their left ran a small Brook , having steep Hills and little Bogs on each side , next to which was a large red Bogg , almost a mile over , at the end of which stood the Castle of Aghrim , commanding the way to their Camp , which was passable no way for Horse , but just at the Castle , by reason of a River , which running through a moist ground , made the whole a Morass or Bogg , which extended it self all along to the Enemies right , where was also another Pass called Vrachree , having a rising ground on each side of it : The Enemy encamped upon the side of a Hill very well Ditched , and the Ditches as well lined with Shot to the very edge of the Bogg , by which it appears they were so well posted , as not to be easily attackt .

Upon Sunday , July 12 , about 6 in the morning , we marcht , but Orders were given , that our Tents and Baggage should remain where they were ; the Foot marched over the Bridge , the English and French Horse and Dragoons , over the Foord above the Bridge , & the Dutch & Danish Horse & Dragoons over two Foords beneath the Church , with directions , as soon as they were over the River , to put themselves in order of Battle which they did on the Lands of Garbally , Rathboy and Dunlow ; in which order ( the morning proving hazie ) we stood till 11 at noon , when the General Commanding the Army to move forward , advanced himself before the Army , to view the posture of the Enemy , and perceiving some of their out-Scouts upon the Hills , ordered a Party to beat them thence , upon whose advance the Enemy retired from Hill to Hill , within half a mile of the Camp , by which means the General had the opportunity from a high Hill on the right of the Enemy , to view their whole Camp , which he found Posted , as before described ; and that he was under a necessity of gaining a Pass to the right of the Enemy , where he perceived some of them posted , to which purpose he ordered a Danish Captain with 16 Horse to force it , who being repulsed by the Enemy , the General ordered to be succoured by 200 of Sir Albert Cunningham's Dragoons , who having secured some Ditches near the said Pass , and having also briskly charged the Enemy , obliged them to retire to a little Grove , whither the Enemy , seeing their danger , had sent a fresh Party to sustain them , which our General perceiving , ordered Collonel Eppinger's Dragoons to get between them and their Camp , which had been effected , but that it was too timely discovered by the Enemy , who had sent out fresh Detachments enough to cut off our Dragoons , but they were quickly seconded by a Party of the Earl of Portland's Horse , who behaved themselves with great bravery , but lost several Men and Horse in this part of the Action , upon which both sides sending fresh Detachments to sustain their Parties , what at first was only a Skirmish , had by this time engaged a considerable Body , and after an hours Dispute , obliged the Enemy to retire in great disorder over the Brook that flanked the right of their Army , without any great loss to us , though the Enemy all the while fired upon us with some of their great Guns from the Hills of Killcommodan .

The General perceiving the disorder of the Enemy , resolved to attack them on their right Wing , by that means hoping to draw off the strength of the Enemy to the Right , and then with our right Wing to fall in upon their left , and thereby engage their whole Army .

The left Wing of our Army being most Forraigners , was Commanded by his Highness the Duke of Wirtemberg , and the Right by the Major-Generals Maccay , Talmash and Ruvigny , the General himself with great diligence moving every where , giving the necessary Orders , and ordering Reinforcements as he saw occasion ; About half an hour after 4 in the Afternoon our left Wing moved towards the Enemy , and by 5 were got up to their Ditches , well lined with the Enemies Musqueteers , which ( notwithstanding their advantageous Post , and their defending themselves better than usually , or than indeed we expected and the opposition made by the Lord Galway's Regiment of Horse , and the Royal Regiment of Foot so called ) Our men soon forced and made them give ground , so that our General 's design had its intended effect , in drawing off most of the Enemies Horse from their Left to succour their Right , which though it much damaged Colonel Earls's , Colonel Herbert's , and Colonel Fowlke's Regiments did yet facilitate the Attack of our Right Wing , which with a good Body of Horse , Foot and Dragoons , forced the Pass by Aghrim Castle , though defended by a Regiment of Dragoons , and so narrow , that our Horse were forced to march it by a Defile of two a breast , receiving the Enemies Shot with no great loss , till at last recovering the firm part of the Bogg our Men formed a Line , and some of them advanced under the Walls of the Castle , and lodged themselves in a dry Ditch , though the Enemy poured Volleys of their small Shot upon them ; the rest of that Brigade with great bravery attackt their Ditches , and pressed so far upon the Enemy , beyond what they ought to have done , unless they had been supported with Horse , that they were forced back to the Bogg , but when they were re-inforced by our Horse ( who charged through the Enemy with Sword in hand , as did also our Horse on the left Wing ) they drove the Enemy to the top of the Hill , where their Horse and Foot mixed with ours , but after a short dispute we totally routed them , and beat their Horse out of the Field , who never drew B●●t for 7 miles , leaving their Foot to be cut in pieces . They began to run as it grew duskish , and our men pursued them about 4 miles : Their Foot were entirely broke , and those who ran away , ( after their usual manner ) threw away their Arms

Aghrim Castle being taken , many there in were put to the Sword , and Colonel Bourke , his Major , 11 Officers and 40 private men were taken Prisoners .

Our General shewed extraordinary Conduct , Diligence and Bravery throughout this whole Action , Our Officers behaved themselves with great Resolution , and so did the Private Soldiers , who were not in the least daunted , notwithstanding all the advantages which the Enemy had over them in number , in their strong Entrenchments , or in the difficulty of attacking them . In short , never did Army fight better , nor can we find Actions fitter to compare with this , than those of their own former performance , viz. the forcing of the Boyne and Shannon .

Our loss , considering the greatness of the Action , was not very much , having but 62 killed , among whom were Major-General Holstaple , Colonel Herbert , Colonel Mongatts , Major Deverish , Major Pettit , Major Colt , Major Cornwall and Major Fox , with several Captains and Subalterns , and about 950 wounded , 4 parts of 5 whereof , will be easily cured , and soon fit for Service .

In this Action we took from the Enemy 11 Standards , 32 Colours , all their Cannon , Ammunition , Tents and Baggage . We killed also of the Enemy about 7000 , and took about 450 Prisoners ; The Principal of those killed and taken Prisoners are as followeth , viz.

General and Field Officers , 24 Captains , 26 Lieutenants , 24 Ensigns , 23 Cornets , 5 Quarter-Masters . 4 Adjutant , 1 — Officers Prisoners , 107 — Privste Soldiers , about 300 —
