Augusta, Sicily
Through scrounging spare parts from sunken craft, the battered flotilla is able to piece together three seaworthy craft. Jeffords' mission is to destroy a former Italian submarine base in Augusta, Sicily, that now contains the German's Fritz X glide bombs that have been taking a heavy toll of British shipping. As the bombs are stored in former submarine pens tunnelled inside a mountain, an aerial attack is unfeasible. It is up to Jeffords to determine how he will accomplish his mission.
