Whakaotihia te rerenga e whai ake nei: I whanau te tama a Major Guy Melvil Gibbs me Margaret Gibbs (née St John) ka kuraina i te Eton College me te Royal Military College, Sandhurst, i whakauruhia a Gibbs hei tuarua tuarua ki te Kings Royal Rifle Corps (KRRC) i te 31 o Tihema 1939, tata ki te wha marama i muri i te urunga mai o Ingarangi ki te Pakanga Tuarua o te Ao. Heoi, kaore ia i uru wawe ki te mahi, i te mea i kiia he tamariki rawa ia, ka noho ki te United Kingdom kia tukuna ra ano ia ki te 2nd Battalion, KRRC, i whakahaua e Lieutenant Colonel George Erskine me te tukanga o te whakahou i muri i te mamae nui i te whakapae o Calais. I whakatairangahia a Gibbs ki te rangatira i te 1 Hōngongoi 1941, ka mahi ia me te roopu mo te toenga o te pakanga, ka tukuna ki Awherika ki te Raki me tana roopu i te mutunga o te tau 1941, ka whakawhiwhia ki a ia te Military Cross (MC) i te 15 o Oketopa 1942. Whai muri i tana whai waahi ki te Pakanga Tuarua o El Alamein, i riro ia ia te rangatira o te 'C Company' o tana peihana i te Poutu-te-rangi 1943 ka noho tonu ia ki taua mahi mo te toenga o te pakanga. Ko te whakahau i tana kamupene puta noa i nga waahanga whakamutunga o te Campaign Tunisian, i uru atu ki te whakaekenga a Allied o Itari, nga whakaekenga o Normandy me nga whakaekenga whai muri
whawhai i te raki o te uru o Uropi tae noa ki te Wikitoria i te Ra o Uropi (VE Day) i Mei 1945. I tēnei wā katoa, mai i te Rā D ki te Rā VE, ko Edwin Bramall tētahi o ōna hoa rangatira. Ka rite ki a Gibbs anō, i whakaritea a Bramall kia eke ki ngā taumata tiketike rawa. I whakawhiwhia ki a ia te Tohu Ratonga Motuhake (DSO) i te 2 o Akuhata 1945.
