Documentary | 05 November 1944

This Royal Navy instructional film was released in February 1944 to emphasise the need among serving personnel to understand the potential consequences of even minor negligent acts. The narrative walks viewers through the considerations and efforts behind building a heavy cruiser. It then details examples - such as leaving paint, books, towels and posters unsecured - presented potential risks in an emergency scenario. It shows how the cumulative effect of these mistakes impaired the fighting efficiency of the fictional cruiser "HMS Andromeda", turning minor battle damage into a critical situation - and preventing the cruiser from moving to intercept an enemy vessel.
