A service at Liverpool Cathedral has been held to honour those killed in The Battle of the Atlantic.

It was part of a weekend of events commemorating the longest continuous military campaign in World War II.

The service, attended by the Princess Royal, was followed by a march to remember the thousands who lost their lives during the battle.

It fought for control of vital supply routes, beginning as war broke out in 1939.
