Whakaotihia te rerenga e whai ake nei: I nga tau i muri mai, ko Montagu te hoa tata o Edward. I te Paenga-whawha 1331, ka haere nga tokorua ki te haerenga huna ki Parani, i te mea he kaihokohoko kia kore ai e mohiotia. I te marama o Hepetema o taua tau ano, i whakahaerehia e Montagu tetahi whakataetae i Cheapside, i reira ia me te kingi i whakakakahuhia hei Tatars. Mai i te tau 1333 ki muri, i hohonu a Montagu i roto i te
Scottish Wars, ā, i whai mana ia i te Siege o Berwick me te Pakanga o Halidon Hill. I muri i tenei huihuinga i mohiotia ai tana rangatira mo te Moutere o Man, he tika i riro mai i tana tupuna. Heoi, i taua wa he kaupapa noa te rangatira, i te mea kei raro tonu te mana o Scotland i te moutere.
