[2] During the Battle of Affane in 1565, Edmund wounded Gerald FitzGerald, 14th Earl of Desmond in the right hip with a pistol-shot, cracking his thigh-bone and throwing him from his mount.

By his father's will, he received the Dullough - the western part of the barony of Idrone, which, with the Roscrea property, was considered to be worth £400 yearly.

But on surrendering his estate to the Queen, 10 October 1570, he was pardoned, (together with his brothers Edward and Piers) dated at Gorhambury 12 March 1573, of all their treasons.

He rather ungallantly fell from a rope hung from the battlements and was forced to spend the night roaming around in the castle fosse evading Sidney's troops.

Some years after Edmund's death, Queen Elizabeth I reversed the attainder on his eldest son Piers, who was granted ancestral lands in Roscrea, County Tipperary.

In 1602, Elizabeth also reversed the attainder on his last remaining legitimate son Theobald, who became the 1st Viscount of Tulleophelim and Governor of County Carlow.
