His career in
Ireland began when in 1598 the
Earl of Essex appointed him Governor of
Carrickfergus, following the death of his brother, Sir John Chichester, who had been killed at the
Battle of Carrickfergus the previous year. It is said that Sir John Chichester was
decapitated, and his head was used as a football by the MacDonnell clan after their victory. James Sorley MacDonnell, commander of the clan's forces at the Battle of Carrickfergus, was poisoned in
Dunluce Castle on the orders of
Robert Cecil to placate Chichester. During the
Nine Years' War Chichester commanded British troops in
Ulster. His tactics included a
scorched earth policy. He encircled the
Earl of Tyrone's forces with garrisons, effectively starving the Earl's troops. In a 1600 letter to Cecil, he stated "a million swords will not do them so much harm as one winter's famine". While these tactics were not initially devised by Chichester, he carried them out ruthlessly, gaining a hate-figure status among the Irish. Tyrone's weakening military position forced him to
abandon and destroy his capital at
Dungannon. Following the signing of the
Treaty of Mellifont, he succeeded
Lord Mountjoy as
Lord Deputy of Ireland from 3 February 1605. A year later in 1606 he married Lettice Perrot, daughter of
Sir John Perrot, a former Lord Deputy. Lord Deputy Chichester saw
Irish Catholicism as a major threat to the Crown. He oversaw widespread persecution of Catholics, and ordered the execution of two bishops, including the aged and respected
Conor O'Devany. His relations with the traditionally Catholic nobility of
the Pale, in particular
Lord Howth, who could be quite quarrelsome, were poor. In Howth's violent feuds with the new English settler families, particularly
Thomas Jones,
Archbishop of Dublin, and his son, and
Viscount Moore of Drogheda, Chichester invariably sided against Howth but was unable to completely break his influence as he was a favourite of
King James. Following the
Flight of the Earls in 1607, Chichester became a leading figure in the
Plantation of Ulster. Initially, he intended that the number of Scottish planters would be small, with native Irish landowners gaining more land. However, after
O'Doherty's Rebellion in
County Donegal in 1608, his plans changed and all the native lords lost their land. Most of the land was awarded to wealthy landowners from England and Scotland. However, Chichester successfully campaigned to award veterans of the
Nine Years' War land as well, funded by the
City of London livery companies. == Later life ==
