"The mid of the maintop by Arthur Lee Knight" is a juvenile naval adventure story from the late 19th century Victorian era. Set during British anti-slavery patrols off East Africa, it centers on courage, seamanship, and duty as a frigate’s crew hunts slavers and faces peril ashore and afloat. The story opens with H.M.S. Forte in a storm, where midshipman Jack Villiers is swept overboard and presumed dead. Later, a cutter under young Thring discovers a dhow in the Joo-joo river and, after a rough boarding fight, learns Jack is alive but carried inland by Arab slavers. The frigate launches a naval brigade that storms a fortified village ruled by Sooltan Shah, blasting the gate and fighting hand-to-hand while their officer is wounded. Meanwhile, Jack frees himself by cunning, tunnels out of his hut, hides in a tree, and escapes by canoe downriver. He reunites with the boats as the force withdraws, and the tale closes on fellowship restored after brisk action, narrow escapes, and the disruption of the slavers’ trade.
