The novel describes a life of boredom and sudden battle action, but the chief conflict is between the traditional western ideas, which saw China in racist and imperialist terms, and emerging nationalism. The protagonist, Machinist Mate First Class Jake Holman, the ''San Pablo's'' first assistant (PO3) engineer, teaches his Chinese workers—he refuses to call them "
coolies"—to master the ship's machinery by understanding it, not just "
monkey see, monkey do". The ship is sent to save the China Light Mission from anti-foreign mobs, setting off a debate: "No man who favors the
unequal treaties has the right to call himself a Christian!" Others reply "It is time for the
Society for Propagation of the Gospel to step aside. It is time for the Society for Propagation of Cannonballs to bring them to their senses." After the crew burn and destroy a
war junk, Holman takes a landing party to rescue the missionaries, including teacher Shirley Eckert whom Jake has met several times and come to love. Holman is pinned down and killed, but Eckert is saved. ==Reception and review==
