Kilcash could of course also not fight to suppress the Desmond Rebellions that were started in 1569 by
James fitz Maurice FitzGerald, captain of the Desmond forces in the earl's absence. The captain was supported by many Irish in southern Ireland but also by some of Butler's brothers, notably Edmund. The rebellion was directed against
Henry Sidney the Lord Deputy of Ireland. Kilcash's brother Thomas, Lord Ormond returned to Ireland landing at Waterford in July 1569 whereupon his brothers submitted quickly. However, Edmund, Edward and Piers were
attainted in April 1570 by an act of the Irish Parliament. That meant that Edmund ceased to be Ormond's heir presumptive and John, the next brother, took his place but only for about a month as he died on 10 May 1570. John's eldest son,
Walter, thereafter became heir presumptive. James fitz Maurice FitzGerald surrendered on 23 February 1573 and Gerald followed in September ending the first Desmond rebellion. == Death and timeline ==
