William Wylie was a British Army officer who served as the senior prosecutor during the trials of the Easter Rising leaders in April-May 1916. Wylie was ordered by General John Maxwell to try the Irish republican leaders in a military court-martial (without need for due process or defense counsels), and he chose George Wilson as his junior counsel. With Wilson's help, he obtained evidence that Patrick Pearse was in league with the German Empire, giving General Maxwell the necessary evidence to have Pearse executed.
