"My father, Joseph Clarke, was better known over the countryside by the name of Ironside Joe, for he had served in his youth in the Yaxley troop of Oliver Cromwell's famous regiment of horse, and had preached so lustily and fought so stoutly that old Noll himself called him out of the ranks after the fight at Dunbar, and raised him to a cornetcy. It chanced, however, that having some little time later fallen into an argument with one of his troopers concerning the mystery of the Trinity, the man, who was a half-crazy zealot, smote my father across the face, a favor which he returned by a thrust from his broadsword, which sent his adversary to test in person the truth of his beliefs. In most armies it would have been conceded that my father was within his rights in punishing promptly so rank an act of mutiny, but the soldiers of Cromwell had so high a notion of their own importance and privileges, that they resented this summary justice upon their companion. A court-martial sat upon my father, and it is likely that he would have been offered up as a sacrifice to appease the angry soldiery, had not the Lord Protector interfered, and limited the punishment to dismissal from the army.
Cornet Clarke was accordingly stripped of his buff coat and steel cap, and wandered down to Havant, where he settled into business as a leather merchant and tanner, thereby depriving Parliament of as trusty a soldier as ever drew blade in its service. Finding that he prospered in trade, he took as wife Mary Shepstone, a young Churchwoman, and I, Micah Clarke, was the first pledge of their union." Micah Clarke, a historical romance about the Monmouth rebellion and "Hanging Judge" Jeffries, was Arthur Conan Doyle's attempt to present the story of the Puritans in a more favorable light than was generally current in England. It was a serious success for him, running through several printings.
