The Attorney-General writes in 1606: “The first night we lodged at Mallow, a house of my Lady Norries, which is a well-built house, and stands by a fair river in a fruitful soil, but it is yet much unrepaired and bears many marks of the late rebellion.” At this time Elizabeth Norreys, heiress to the estate, was a king’s ward, and resided with her mother in the castle.
In 1613 a fresh patent was granted to Dame Elizabeth Jephson, and her heirs for £50 paid by her husband, Sir John Jephson, Knight, she having inherited her father’s estate. The grant included the castle, manor, and town of Mallow, Short Castle, alias Castle-Gar, &c.
In 1636 the Earl of Cork made an offer for the manor, but he did not come to terms with the owners.
Short Castle, which was on the north side of the town, was in charge of Lieutenant Williamson in 1641, when Lord Mountgarret marched against Mallow, while the larger fortress was placed in charge of Arthur Bettesworth and two hundred men by Captain Jephson.
After many assaults and several breaches, Short Castle was forced to surrender, which its commander did on terms. There are several versions of the following story.
After the castle’s fall its defender and his men were refreshing themselves in a public-house in the town, when an officer and man belonging to Mountgarret’s force entered with a block and sword, stating they had come to behead them. Lieutenant Williamson caught the sword up with one hand and the officer’s hair with the other, and dragged him to the walls of the larger stronghold, where, dismissing him with a kick, he and his men joined the other garrison.
The Castle of Mallow was taken by the Earl of Castlehaven in 1645, and almost reduced to ruins.
In 1666 there seems to have been an attempt made to restore it. Lord Orrery, writing to the Duke of Ormond in this year, says: “This bridge is at Mallow, where there is a castle of good strength if it had a little reparation, and is one of the greatest passes and thoroughfares in this province, and if seized on by any enemy would, in effect, divide the country into two parts.”
During the scare of the French invasion the Grand Jury presented money to repair it, but the Judge seems to have reserved his decision on the matter.
Major-General Sgravenmore sent Colonel Doness to destroy the bridge and reconnoitre the castle in 1689.
