"Many of our readers are doubtless aware that the field of Aughrim was fought upon a Sunday, a circumstance which added one to the many thrilling incidents of the martial scene. The army had hardly moved into that position which was that day to be so hardly and devotedly maintained, when the solemn service of high mass was commenced at the head of every regiment by its respective chaplain; and during this solemn ceremonial were arriving at every moment fresh messengers from the outposts, their horses covered with dust and foam, with the stern intelligence that the enemy were steadily approaching; and amid all this excitement and suspense, in silence and bare-beaded, kneeled the devoted thousands in the ranks in which they were to receive the foe, and on the very ground on which they were in a few hours so desperately to contend. This solemn and striking ceremonial under circumstances which even the bravest admit to be full of awe, and amid the tramp and neighing of horses, and jingling of accoutrements, and the distant trumpet signals from the outposts, invested the scene with a wildness and sublimity of grandeur, which blanched many a cheek, and fluttered many a heart with feelings very different from those of fear."

The Pass of Urrachree.

A thick vapor, called up from the surrounding bogs and marshes by the hot morning sun, kept the rival armies concealed from each other's sight till about 12 o'clock, when, all becoming clear, the men on Kilcomedan had a full sight of the allied forces, commanded by eight majors-general, and arranged in double columns, their rich appointments presenting an unpleasant contrast to their own much more modest if not shabby garb and accoutrements. As soon as General Ginckel could command a distinct view from a height toward the left of his lines, he was enabled to judge of the strength of the position held by the Irish, and the skill shown in the disposition of the forces adverted to above. He could see one portion of the cavalry prepared to dispute the pass at Urrachree, another watching the pass at Aughrim, the main body of horse posted below the crest of the hill, the infantry still lower disposed in two columns, and he could guess the presence of musketeers in the ditches at the bottom of the hill, prepared to receive the hardy infantry who would venture across the morass to exchange shots with them. Sarsfield's horse beyond the brow of Kilcomedan on the Irish left, he probably did not observe. There was the shrewd and fiery chief placed, with strict orders from his unfriendly superior not to stir from that spot till expressly ordered. Had the gallant Dutchman at that moment known that St. Ruth had not communicated to any of his general officers the scheme be intended to observe through the engagement, his hopes of victory would have been much more sanguine. Feeling the inexpediency of commencing a general engagement, yet impatient of the scene of inactivity before him, he gave orders to a Danish captain of horse commanding sixteen men to attempt the pass of Urrachree. The small body was warmly received by some watching cavalry still fewer in number, and though the brave officer justified the reputation of his country for dogged courage, his men were deserted by that virtue so essential to every soldier, and "ran like men."

Ginckel, fully aware of the importance of the pass in case a general engagement should take place, next directed Colonel Albert Conyngham to take possession of some ditches near where one branch of the stream entered the morass. The chief of this party had received orders not to advance beyond the mere boundary, lest he should be intercepted, and thus bring on a premature engagement. The Irish party, after receiving the enemy's fire and returning it, showed their backs, and their assailants pursued them beyond the limits pointed out by the sagacious De Ginckel. An ambush had been prepared in expectation of this proceeding, and, while they were least expecting it, a destructive fire was opened on them from behind cover. Many immediately dismounted, and, taking advantage of a hedge, returned the fire with deadly interest. They had little time to enjoy the success of this move, when they were startled by the rush of a strong cavalry force sweeping down on them from behind the extremity of the hill, and the old manor-house of Urrachree. They were obliged to retire in disorder before this new enemy, but the watchful eye of the justly displeased general had well marked the progress of the action, and provided for the expected repulse. D'Eppinger's royal regiment of Holland dragoons came on amain to get between the pursuing Irish horse and the hill. But other detachments of Irish cavalry were at hand to frustrate this design; the Earl of Portland's horse were sent to support the forcing party, and a stern combat was waged for about an hour, fresh parties joining the strife from the natural impatience of men of heart to remain still while blows are bandying before their eyes. At three o'clock this contention came to an end, both sides having lost several stout partisans, and the relative positions being much the same as at the beginning of the skirmish.

For the next hour and a half nothing was done on either aide. The English generals were in close consultation as to whether it were better to renew the attack or defer it till next morning. The brave old Scotchman, Mackay, decided his fellow commanders for present action. He counselled a renewed and more effective attempt at Urrachree, which, causing re-enforcements to be drawn from the Irish centre and the neighborhood of Aughrim, would enable the infantry to try the morass where it was narrowest, and also enable the cavalry on the right wing to force the dangerous pass at Aughrim, watched by the garrison of the ruined castle.

The Morass And The Hedges.

At this time (half-past four in the evening) the main body of the English formed two lines directly before the morass, the generals on each side having a pretty correct idea of the state and efficiency of their foes. In other respects the advantage was with the allied army. There was a perfect cordiality and understanding between De Ginckel and his generals, and even in the case of his death and that of his second in command the Duke of Wirtemberg, Mackay, or Talmash, or De Ruvigny were perfectly apprised of the general plan of the action.

The Danish horse and a body of infantry were ordered to the extreme left, with the apparent design to out-flank the enemy on that side, and thus draw away from the Irish centre and left wing much of the strength there needed. This body (the Dutch, to wit) kept that postilion during the remainder of the battle, doing as good service as if actually engaged. Three French regiments, namely, those of La Mellonière, Du Cambon, and Belcassel, commenced to assail the advanced forces of the Irish in the neighborhood of these inactive troops, and obliged St. Ruth to weaken his left and centre to support them. Except the cannonading from both sides there was no fighting going on until six o'clock along the entire line, except this in the neighborhood of Urrachree.

Mackay, in order to weaken still more the Irish left wing, advised Ginckel to separate a considerable body of horse from Talmash's troops, who were waiting for a favorable opportunity to tempt the narrow pass toward Aughrim, and to send them toward Urrachree. This had the desired effect, and now preparations were made to cross the morass at the narrowest part and attack the Irish centre.
