New record images create the most complete set of records to identify the over 5.5 million soldiers served in the British Army during World War I. This is a large topic, but research has gotten easier during the last couple of years as original resources and indexes have become available online, and new finding aids have been created. This lecture examines what records were destroyed during WWII, what records survived along with how to use the new indexes, online originals and how to interpret them. Plus put the soldier’s actions into battle context.
