John’s first return to Parliament in January 1390 was almost certainly engineered by his father, who was then himself representing Cumberland for the fifth and last time in the Lower House. As a busy public official, Amand Monceaux was concerned with the presentation of a parliamentary petition for the reduction of farms and taxes in the north, and he may also have been anxious to pursue private interests at Westminster. The precise dates of his term as mayor of Carlisle are not now known, but it looks as if he held office over the year ending October 1391, and was thus ideally placed to secure his son’s election, for a second time, to the Parliament which met in early November of that year. It is, however, important to remember that John commanded a good deal of influence in his own right. In February 1390 (while his first Parliament was still sitting), he was named among the witnesses to a conveyance of land in Shap by Hugh Salkeld I; and a few months later he appeared at the assizes in Penrith as an attorney for his mother, Margaret, who was involved in a dispute over property in Cumberland. When, in 1394, his father sued out a writ of supersedeas to halt an action of account brought against him by Sir John Manners, John acted as one of his mainpernors. He also joined with Robert Lowther and William Stapleton in standing surety in the court of Chancery for a chaplain accused of harbouring felons.
Somewhat surprisingly, in view of his own and Amand’s evident fall from grace, John took part in Richard II’s ill-conceived expedition to Ireland in the summer of 1399, naming Sir William Curwen and Geoffrey Tilliol as his attorneys while he was away. He served in the retinue of the duke of Exeter, and thus evidently incurred the displeasure of Henry of Bolingbroke, whose coup d’état placed him in a rather vulnerable position. His father may not have lived to see him summoned, along with Curwen, the Cumbrian landowner, Thomas Sands, and six other northerners currently viewed with suspicion, to appear before Parliament at Westminster ‘for particular causes specially moving the King and council’, but since these orders were issued twice, in September 1399 and again one year later, he evidently escaped punishment.
