Hi Daan
For the benefit of others here is the photo in our Gallery that you refer to http://gallery.commandoveterans.org/cdoGallery/v/units/Royal+Marine+Commando+Units/48+RM+Cdo/48+Cdo+officers+jr.jpg.html
We have several references to your Uncle in our Archive as well if you go to the main archive home page and search on his surname. His name also appears in the book 44 Commando, From Achnacarry to the Arakan, author Tony Mackenzie. On page 121 of my copy at Ahmadnagar in June 1945 the author records that
Lts. S.L. Fouche and D. Ranger from the South African Union Defence Force and 13 marines joined 44 as replacement personnel.
On page 122 the author records that
On 20th June an advance party (Lt. Fouche) left for Kharakvasla.
On page 125 the author records for the 6th August that Lt. Fouche of 'A' Troop was wounded by grenade shrapnel during practise assault landings and night exercises.
If you have a photo of your Uncle please post it here and can you include his full forenames.
