"The Sea Hawk" (1940) was originally intended to be a new version of the Sabatini novel, but the studio switched to a story whose protagonist, Geoffrey Thorpe, was loosely based on Sir Francis Drake, although Drake was never a galley slave. Howard Koch was working on the script when war broke out in Europe, and the final story deliberately draws vivid parallels between Spain and the Nazi Reich. The existence of galley slaves and the misery they endure is set up as a metaphor for life under the Reich. When Thorpe (Errol Flynn) liberates a Spanish vessel full of English captives, the freed men row willingly for home to “Strike for the Shores of Dover”, the stirring music of score composer Erich Wolfgang Korngold and lyrics by Howard Koch and Jack Scholl. The first verse “Pull on the oars! Freedom is yours! Strike for the shores of Dover!” evoked the recent evacuation from Dunkirk. The sets in the 1940 film appear historically accurate.
