Oueen Elizabeth desired the Lord Deputy to exchange some of the crown lands with Henry, Earl of Kildare, for the castle and lands of Carlow in 1589. During the unfortunate Essex’s rule in Ireland, in 1598 to 1600 the Queen’s warders held the fortress, but the Kavanaghs laid the surrounding country waste.
By the State Papers of 1604 the manor of Carlow was granted to Donagh, Earl of Thomond, with the exception of the castle, of which, however, he and his son were made constables. The following is taken from a document setting forth the conditions of the grant:—
“In all works made within the castle, the inhabitants of Carlow are to find six workmen or labourers daily, during the said work, at their own expense; also each tenant and cottager to weed the demesne corn yearly for three days, and a woman out of every house in Carlow to bind the sheaves for one day; each tenant and cottager to cut wood for the use of the castle for three days in summer, and each of them having a draught horse to draw the wood to the castle for three days, also to draw the corn out of the fields to the area of the said castle for three days; to give one cartload of wood, and one truss of straw at Christmas and Easter.”
Shortly after this the castle and bawn was granted to Sir Charles Wilmot.
Five hundred English were besieged in the castle in 1642, and were in a starving condition when relieved by Sir Patrick Wemys, who had been despatched to their relief by the Earl of Ormond. The rebels burned the town and fled at his approach.
In 1647 the King’s garrison was so hard pressed that the Earl of Ormond borrowed £60 for its relief, and forwarded it by Major Harman, but the fifty men who came to reinforce the garrison could not get in, as the stronghold was closely invested. The siege lasted about a month, and then the castle surrendered.
In Dr. Jones’ diary he states that the Cromwellian army arrived before the castle on the 18th of March, 1649. That the garrison of two hundred men refused to surrender it until the battery played on the place, and preparations were made for storming.
The next day the castle was surrendered, and two companies left to garrison it. The officers in command being Colonel Hewson, Sir T. Jones, and Colonel Shelburn.
Again we learn that Ireton arrived to take the castle on July 2, 1650, and that he spent the whole day in preparing for the attack. The troops encamped on the Queen’s County side of the river, the field still being pointed out. They had to erect a temporary bridge of ropes, hurdles and straw to cross the river, and the soldiers passed over one by one.
In Edmund Ludlow’s “Memoirs” he describes the place as “a small castle, with a river running under its walls,” and ascribes its importance to the fact of the neighbourhood being in sympathy with the garrison.
