Whakaotihia te rerenga e whai ake nei: I te wa i rite ai a Margaret, tana tama me tana hunaonga (Anne) ki te whai i a Warwick ki Ingarangi, kua huri ano nga teepu ki te painga o nga Yorkists, a ka hinga te Earl ka patua e te Kingi a Edward IV i te hokinga mai i te pakanga o Warwick.
Te Pakanga o Barnet i te 14 o Paenga-whāwhā 1471. I akiaki a Margaret ki te arahi i tana ope i te Pakanga o Tewkesbury i te 4 o Mei 1471, i te wa i hinga ai nga ope o Lancaster, a i mate tana tama tekau ma whitu-tau a Edward o Westminster. Ko nga ahuatanga o te matenga o Edward kaore ano kia maarama; kaore i te mohiotia mena i mate ia i te whawhai tonu, i whakawakia ranei i muri i te pakanga e te Duke o Clarence. I roto i nga tau tekau o mua, kua rongonui a Margaret mo te riri me te tutu, engari i muri i tana hinganga i Tewkesbury me te matenga o tana tama kotahi, i tino pakaru ia i roto i te wairua. Whai muri i tana whakarau a William Stanley i te mutunga o te pakanga, i herea a Margaret ma te whakahau a Kingi Edward. I tukuna ia ki Wallingford Castle i te tuatahi, katahi ka nekehia ki te pourewa o Ranana, he haumaru ake. I mauheretia hoki a Henry VI ki te pourewa i muri o Tewkesbury a ka mate ia i reira i te po o te 21 o Mei; kaore i te mohiotia te take o tona matenga, ahakoa i whakapaehia he regicide. I te tau 1472 i whakanohoia ia ki te tiaki o tana wahine rangatira o mua, a Alice Chaucer, Duchess of Suffolk, i reira ia i noho ai tae noa ki te utu a Louis XI i te 1475.
