The reception of the troops by the inhabitants was enthusiastic, for many, under fear of death, had already abandoned their houses to embark in fishing boats, and escape from a place which they expected to become an immediate scene of savage violence.
During the two succeeding days (7th and 8th of June) the commanding officer was engaged in making dispositions for the defence of the town and in selecting a position. Ground was marked out capable of being occupied by a body of troops so limited in number as the garrison; and while such fences were preserved as would afford cover to the royal light troops from which to annoy an advancing enemy, others that could neither mask their movements or interrupt the play of the guns were levelled and removed. Meanwhile the country was carefully patrolled, and alarm posts assigned to the different corps to take up on the rebels being reported to be in motion.
The morning of the 9th came. At noon a wing of the Durham Fencibles marched in under the command of an excellent officer, Colonel Skerrett, affording a well-timed and most effective reinforcement to the garrison, and, in consequence of this arrival, General Needham made a slight change in his dispositions, and never was a little army more curiously composed than the morning state of that of Arklow exhibited on the day of the attack upon the town.
As the evening came on, an advanced picket announced the appearance of the insurgents, and consequently an infantry outpost at the Charter-house was called in and replaced by a cavalry patrol, while by the two great approaches to the town—the seaside road and that leading to Coolgreney—dense masses were seen moving to the attack. By the former road one great column directed its march against the lower part of the town called the Fishery; by the latter an immense mass, under the command of Father Murphy of Ballycanoo, threatened the upper part of Arklow, and thus endangered the right and rear of the royalist position. To deploy their unwieldy masses appeared to be a task beyond the power of their leaders, for more than half an hour was consumed in the attempt, and when they did effect the change the line was irregular and disordered, at some parts merely in rank entire, and at others six files deep.
The royalists were already in position, the line being slightly curved, the flanks refused, and each protected by battalion guns, with two six-pounders nearly in the centre. The hedges were lined by the Suffolk and Tyrone Militia and part of the supplementary yeomen, with a small party posted in the churchyard and another at the bottom of the street which looked upon the bridge. These posts were occupied to defend the lower town. The barrack walls had been provided with a ‘banquette’ (a wooden stage attached to high walls, at an elevation which will allow the defenders to fire over the parapet), and supplied with musqueteers, while the upper end of the street was barricaded with carts and lumber, and defended by part of the Antrim regiment and a field-piece. Generally the cavalry were formed on the bridge and sands. Taking the local character of the place and the small number of its defenders into consideration, the disposition of the troops was very judicious and creditable to General Needham.
The actual strength of the rebel army was, on the lowest calculation, computed at 25,000 men, and on good authority it has been even raised to 31,000. About 5000 of the insurgents, were armed with firearms, and they brought two well-appointed guns into action. But it was not from their enormous numbers only that they were formidable. They came forward under the wildest enthusiasm, burning to exact vengeance for past defeats, and confident they must annihilate the small but daring body who, undaunted by a twenty-fold superiority, were steadily awaiting their attack. During the morning’s march from Gorey they plundered the houses of the Protestants of everything valuable, putting in requisition all the spirits and provisions that could be supplied; and, under the double influence of intoxication and fanaticism, were led on by their priests, who inspired them with ideas of their own invincibleness; because, as they assured the misguided wretches, they were engaged in the cause of heaven, and opposed to the enemies of God. To maintain that religious frenzy which was their great source of courage, at the end of every mile during the march their leaders said mass, and used every mode of exhortation and every superstitious device that priestcraft could invent. They advanced in an irregular line, which was frequently broken by their running out to file along the hedge-rows lying parallel to the position of the king’s troops, of the cover of which they endeavoured to avail themselves. Their front rank was composed of those who had firearms, and were mostly from the barony of Shelmalier, on the Wexford coast, where they subsist during the winter by shooting sea-fowl, which makes them expert marksmen. They were covered in the rear by the pikemen, many deep, while at certain intervals the line was strengthened by numerous masses of men, who were ready to supply the places of those who fell, or act as occasion might require. Each company had a green flag about two feet square, with a yellow harp in the centre, while some were parti-coloured, and equal in size to the king’s colours. Their leaders were distinguishable riding through the ranks, marshalling them and giving orders. During the engagement the rebels frequently repeated their dreadful yells, which heightened the terrific appearance of a numerous host of barbarians, who seemed confident, from superior numbers, that they could easily overwhelm the small army that opposed them.
The rebels advanced two guns by the Coolgreney road, under a sharp and destructive fire from those on the right of the Durham regiment, and the third in position at the barricade. Both of the former were dragged up by lanes on the high road and placed on high grounds, one looking on the centre of the royalist line, the other commanding its left flank.
Although tedious in their formation, the insurgent column directed against the lower town advanced so rapidly that they had nearly succeeded in cutting off a cavalry patrol, which saved itself, however, by swimming the horses across the Ovoca. Having fired the houses in the suburb, the rebels pushed on under cover of the smoke, but they never could gain the bridge, as the fire of the detached party, which covered that approach, and the second, which held the churchyard, cut down the head of the column, and finally disordered it so much as to allow the cavalry, formed on the sands, to charge with excellent effect. During a long and desperate struggle the troops behaved with a steadiness and determination which enabled them not only to secure the lower town, but to inflict a destructive loss upon the assailants.
But the grand effort of the insurgents was directed against the left and centre of the position and the barricade that covered its right flank. From behind the hedges the rebels kept up a steady and well-directed fusilade, and also commanded the royal line with such effect as to dismount a battalion gun and oblige Colonel Skerrett to advance his left wing and protect it behind a fence from the fire of a field-piece, which otherwise must have enfiladed it. The gallantry of the Durham Fencibles was unbounded. Thrice the rebels came forward in immense force against the wing of this noble regiment, and as often a destructive volley from their musketry, with grape from the battalion guns, obliged the assailants to recede from a fire they found intolerable. But, maddened by intoxication and encouraged by their ghostly leader, the deluded wretches again and again returned to the attack, and the General, despairing of repulsing the continued efforts of desperate savages, determined to yield the ground and abandon the position. Colonel Skerrett, well aware that to retire with a handful of beaten troops in the presence of five-and-twenty thousand men would lead to their total destruction, as sternly resolved to hold the post he had taken to the last; and an unforeseen event decided the fortune of this doubtful day, and crowned the gallant few with well-merited victory.
As long as the redoubtable Murphy of Ballycanoo—who hitherto seemed to bear a charmed life—remained to lead his demented and infatuated followers, all that the assailed could effect was to frantically hold their ground, their assailants continuing to rally after each repulse. It may be judged how critical was the situation of the defending royalists. Murphy, as described, had led his legions within a few paces of the barricade, and was encouraging his adherents by waving his famous banner of ‘Death or Liberty’ at the head of the advancing hordes he was leading to the charge, when a round-shot from one of the Durham guns struck him down; the invincibility charm was broken, and the rebels fled dismayed. About eight o’clock, when it was growing dusk, they began to retreat towards Coolgreney in an irregular and disorderly manner, carrying off nine cart-loads of dead and wounded. Had the cavalry but had sufficient daylight to have pursued them, they must have cut off great numbers in the retreat.
