pardon. He served in the large English army which invaded Scotland in August 1400. This army was led by the King in person: Henry IV hoped to take advantage of the serious political divisions in Scotland to persuade the aged and infirm King Robert III of Scotland to acknowledge the King of England as his feudal overlord, a claim which the English Crown had revived periodically over the centuries, but which the Scots had always rejected. It is unlikely that Jenico's military skills were needed during the campaign, as the Scots army prudently refused to give battle, and Henry, who was anxious to maintain the image of a benevolent overlord, gave strict orders that there should be no looting or pillaging. After a fortnight the English army withdrew from Scotland, having accomplished nothing. Jenico was made Constable of Dublin Castle in about 1401, and he subsequently became High Sheriff of Meath and one of the Keepers of the Peace for the County, Seneschal of Ulster, and Admiral of Ireland. He did not as might have been expected (as he was by then probably the senior military commander in Ireland) play any role in the Battle of Bloody Bank in July 1402, in which the people of Dublin scored a decisive victory over the O'Byrne clan of County Wicklow. Leadership of the Dublin men was entrusted to the Mayor of Dublin, John Drake, who became a popular hero as a result. Jenico himself is said to have been fighting in defence of his wife's lands in County Meath at the time. He was appointed a member of the council which advised the King's son, Thomas of Lancaster, 1st Duke of Clarence, who was Chief Governor of Ireland from 1401 to 1413. He was given charge of Trim Castle, and manor, and complained in 1403 that the manor tenants were not paying their rent. He acquired substantial lands in Counties Meath, Louth, and Down; his principal seat was at Ardglass in County Down. His marriage in about 1401 to the County Meath heiress Joan Taaffe, widow of Chief Justice Rowe, made him a prominent member of the Anglo-Irish gentry of the Pale as well as bringing him further lands in County Meath. The Earl of Ormonde, who had once quarrelled with him over the right to hold lands in Somerset, was now anxious to be his friend, and made over to him
