Other titles:
Summary: Naval instructional film using animated models to illustrate a U-boat attack on a convoy.
Description: Same format as ADM 1166. The film describes how a U- boat torpedoed and sank an escort destroyer, but was itself sunk by a sloop which first located the submarine by a combination of a square search manoeuvre, snowflake flares, and Asdic. The film concludes that the success of the counterattack "... was mainly due to the commanding officer of the sloop taking immediate action according to prearranged plans".
