Argyle met some members of House Jasper when they traveled to Paps in a diplomatic capacity in 284 AC, but it wasn’t until 285 AC that he made a strong impression. After a trial of seven was ordered by Lord Jasper to resolve the issue of whether Ser Cortnay had murdered Ser Hoster Woodhull in a joust the accused and the accuser (James Woodhull) set about recruiting champions to fight for their causes. Argyle agreed to fight for Cortnay. As the fighting unfolded in the trial Argyle dueled with a mystery knight, later revealed to be Ser Darron, under the Bridge of the Andals. Their fighting ceased when Ser Cortnay was killed.

When Mya Elesham elected to ambush House Woodhull in February of 286 AC it was Argyle that commanded the soldiers. He commanded the men to fan out and encircle the party from Woodhull (James Woodhull, The Blackfish, and Iggy) and rode out to duel Ser James. Ser Carsen also rode out to duel the Blackfish but was disarmed and turned tail quickly. James was wounded and arrested by Argyle, bringing the fighting to an end. Days later Lady Mya told him to begin to prepare the troops to sail for the land, as he is to lend their support to the Jasper cause in an upcoming war.

The final bout of the Spring Tournament of 288 AC saw Ser Argyle, Champion of the Fields, Ser Darron, Champion of the Sun, and Ser Leo, Champion of the Rains faced each other. A terse melee followed in which each man dished out and received substantial pain. In the show of martial prowess the oldest amongst them, Ser Darron, was victorious and named Champion of Spring. Lords Arryn and Royce raised his arms high as the crowd chanted ‘Darron!’, as the other two were helped from the proving grounds by Maesters.

Ser Argyle was eliminated from competition on the next to final day at the Pebble Tourney in 288 AC.
