Hi,
Has anyone information what FA A could have been active in this period in spotting for the artillery in the region of Trezennes-Aire (between Bethune and St Omer), concerning the bombardment by artillery of the Allied aerodrome of Trezennes ?
This question comes from another WW I forum it's administrator, which is left unanswered, and this place is probably the last chance of finding a solution for this.
Thanks and best from Johan
