His political career advanced rapidly, and in the
Irish Parliament of 1585–6 he was returned (along with Edward Brennan) as one of the two members for the newly created
borough of
Callan. He used his growing influence to recover lands confiscated from his relative Henry Comerford, which had been acquired by Francis Lovell, former
High Sheriff of County Kilkenny. His career suffered a brief setback in 1587, owing to his hostility to Sir
John Perrot, the
Lord Deputy of Ireland. Comerford was a member of the faction who worked for the downfall of the Lord Deputy, and he was briefly imprisoned on this account. After Perrot's recall to England in 1588, Comerford earned the goodwill of
Sir Richard Bingham, the
Lord President of Connaught, and was appointed a member of his Council. He seems to have had a vaguely defined role as Crown representative in North
County Mayo, and clashed repeatedly with the Burke family, who were very powerful there. In 1588, following the defeat of the
Spanish Armada, Comerford was given the task of tracking and reporting on the movement of the surviving ships as they made their way down the west coast of Ireland, although he did not have enough men to confront them. He was a highly conscientious official: Bingham later paid tribute to his fifteen years unpaid work as Attorney General for Connacht. In 1591 he visited the English Court, where he was praised for his fidelity to the Queen and appointed Attorney General of Connacht for life. In the same year his old enemy Perrot was convicted of high
treason, and died soon afterwards in the
Tower of London while under sentence of death. During the
Nine Years War the Crown effectively lost control of Connacht, but Comerford showed his devotion to duty by remaining in the provincial capital,
Galway. He relied for his safety on the protection of the
Anglo-Irish loyalist peers, such as
Ulick Burke, 3rd Earl of Clanricarde. In 1597 he reported on the disturbed state of the province. He was given an armed guard, but complained bitterly that his salary was in arrears, and he was obliged to pay the guards out of his own pocket. In 1599 he went to
Ennis and reported back to the Crown on the unsettled conditions he found there. ==Career in Munster==
