"They're just forgotten bones lying far from their homes
As forgotten as the cause for which they died"
Bogle's lines posted above are false.
The cause is not forgotten. They marched to prevent Europe being conquered by the cruel invading armies that poured out of an aggressive Germany.
The anti Fascist cause is alive and well, not least on this forum.

Neither are they forgotten bones.
In all that list of places their graves are carefully kept and attended, and the numbers making the pilgrimage to visit them grows year on year.
And bugles still call for them from sad shires.
