The British army accordingly underwent another transformation. The cavalry, which could not cross at the centre, were posted on the right and left wings. The left wing of infantry was further strengthened by some fresh regiments from the right, while 12,000 infantry were massed against the centre and inner left of the Irish line, to await the result of Mackey's experiment. It was half-past four o'clock, as Ginckle moved forward his left wing of infantry, flanked on either side by his cavalry, determined to reach the ground in front of the Irish line. As they approached the stream which had been the scene of the previous encounters, two Danish regiments, consisting of infantry and cavalry, deployed to the left, along its outer margin, as if intent on turning the extreme right of the Irish position. This, which was a feint on the part of Ginckle, had the desired effect; for no sooner was it observed by the latter, than a corresponding force was detached to counteract it; and, as they continued to wear round in that direction, Ginckle hurled his main body to the assault, across the grounds of Urrachree. This movement on the part of the enemy determined St. Ruth no longer to defer the battle; but by accepting his offer to confine him to the Irish main right, and prevent any discursive movements which should result in weakening it: so, withdrawing his cavalry, he threw forward his infantry to his first line of defence, and awaited the enemy in confidence. As the British advanced, their cavalry was also withdrawn, and thus, as if by mutual agreement, the ground was completely cleared for the action of the infantry on both sides.
