Tuhia he haere tonu mō tēnei wāhanga - I te pakanga o te Aisne
I tīmata i te Paenga-whāwhā o te tau 1917, i whakauruhia te "Escadrille Let 46" ki a Felix Brocard's Groupe de Combat 12 mō te whawhai. I te wā i ārahi ai tō rātau rangatira rangatira, a Didier Lecour Grandmaison, tōna whakakapi, a Marcel Bloch i a rātau e whakakao anō ana, i tēnei wā ki ngā kaipatu pahū e toru o Caudron R.XI. I hoki mai te ingoa o te waahanga ki te "Escadrille C46" i te 17 o Hui-tanguru 1918. I whakahaerehia te roopu hei waahanga o te "Groupe de Combat 15" i te rohe o Champagne tae noa ki te 14 o Mei 1918.
