Total British First World War deaths seemed especially severe as they fell among certain groups such as Pals Battalions (volunteers who enlisted together and were allowed to serve together – and were often killed together) or the alleged "Lost Generation" of public school and university educated junior officers. British deaths, although heavy compared to other British wars, were only around half those of France or Germany as a proportion of the population.
