Tuhia he haere tonu mo tenei irava - I te Pipiri o te tau 1918 i tukuna a Berthelot ki te misioni ki te USA, katahi i te 5 o Hurae ka tohua ia hei rangatira mo te Fifth Army. I whakakapihia e ia a Buat, i whai mana poto i a Micheler engari me whakakapi i a Anthoine (i whakaarohia "he tino pouri" i muri i te parekura tata o te Pakanga Tuatoru o te Aisne
) hei Tumuaki o te Kaimahi Matua i te GQG).
