He was 27 years old, and a private in the 2nd Battalion, The Lancashire Fusiliers, British Army during the First World War when the following deed took place for which he was awarded the VC.

On 2 May 1915 near Ypres, Belgium, when the Germans were advancing behind their wave of asphyxiating gas, Private Lynn, although almost overcome by the deadly fumes, handled his machine-gun with great effect against the enemy, and when he could not see them, he moved his gun higher up the parapet so that he could fire more effectively.

This eventually checked any further advance and the outstanding courage displayed by this soldier had a great effect upon his comrades in the very trying circumstances.

[2] His Victoria Cross is displayed at the Fusilier Museum, Bury, Greater Manchester.

A memorial headstone is in Grootebeek British Cemetery, bearing the inscription: WHO WAS BURIED AT THE TIME IN VLAMERTINGHE CHURCHYARD BUT WHOSE GRAVE WAS DESTROYED IN LATER BATTLES A PLACE IS VACANT IN OUR HOME THAT NEVER CAN BE FILLED.
