Whakaotihia te rerenga e whai ake nei: Mai i te Hanuere ki te Paenga-whawha 1944 i haere a Heaney ki te United States Army Command and General Staff College i Fort Leavenworth, Kansas. I muri mai ka mahia e ia nga mahi whakahaere i runga i te tuku ki British East Africa. Mai i te 1946 i mahi ia i te Mandatory Palestine, he pou i uru ki te waa o te
1947-48 pakanga ā-iwi. I whakawhitihia a Heaney mai i tana komihana whawhai ki tetahi komihana tuuturu i te 1 o Hanuere 1947 ka whakatairangahia ki te rangatira rangatahi (he rite ki te rangatira) i te marama e whai ake nei. I te 20 o Poutu-te-rangi 1947 i whakawhiwhia ki a ia te Tohu Tohu mo te ratonga roa, i taua wa i mau ia i te taumata o te rangatira matua mo te wa poto (he rite ki te rangatira nui).
