In the summer of 1924, Soviet playwright Sergei Tretyakov took up a one-year appointment as Professor of Russian at the University of Beijing. He returned with material that resulted in the 1926 play Roar, China!, based upon a historical incident in Wanhsien in which an American businessman drowned after an argument with a local boatman. The captain of the British gunboat Cockchafer, which happened to be in the area, demanded that when the ferryman could not be found and executed, two other men be executed instead or he would bombard the town.
