I muri i te pakarutanga o te Pakanga Tuarua o te Ao, i tukuna a Biggs hei rangatira mo te 1940; i whakawhiwhia ia ki te Tohu Ratonga Motuhake (DSO) i taua tau mo ana ratonga i te Pakanga Tuarua o Narvik
, a i whakawhiwhia ki a Bar ki te DSO mo tana mahi i te tangohanga o Kariki i te tau e whai ake nei. I whakawhiwhia hoki ia ki te War Cross, 3rd Class mai i Kariki me te Cross of Valour o Poland i te 1942. I mahi a Biggs i te Pakanga o Krete, i mua i tana tuku ki te Admiralty hei Kaiawhina Naval Tuarua ki te Ariki Moana Tuarua (1942 <unk> 44). I whakatairangahia ia ki te rangatira i te 1943, ka whakahau ia mai i te 1944 (ko ia hoki te Tumuaki (D), 11th Destroyer Flotilla o te Tairāwhiti Tairāwhiti), e mahi ana i te Moana Inia.
