The raiding party sail around the coast in a decrepit and barely seaworthy barge; they set mines on the hull of the German ships in Goa. They then board one which is being used to transmit signals to U-boats, catching the depleted crew off-guard. Despite Pugh's order that there be no shooting, several German sailors are killed. The ship is set alight and the party withdraws, watching as the ships sinks. The final scene show a surfacing German U-boat which is expecting to hear a signal from the now sunken ship.
