Whakaotihia te rerenga e whai ake nei: E kiia ana ko ia he Kapene i roto i nga hoia a te Earl o Leicester, e whawhai ana me te tono mai a Elizabeth I, me raro i te haki o Henry o Navarre. I whakaarohia kua mate ia i te
Te Pakanga o Ivry, France i te tau 1590. Heoi, i tuhituhi a Reverend Cotton Mather o Boston: "Ko te papa o Thomas Dudley ko Kapene Roger Dudley, - i mate i roto i nga pakanga, i te wa - ko tana tama, me tana tamahine kotahi anake he tino iti". Ko te hiahia a Thomas Dorne (Thorne) o Yardley Hastings, Gent., i te 29 Oketopa 1588, i tukuna "ki nga tamariki a Susan Dudley, taku Tamahine, pouaru, £ 10 kia tohatoha rite". (S1, S11). Na reira, i mate a Roger i te wa o te hiahia o tona hungawai, i tuhia i te 1588, ka whakakore i te Pakanga o Ivry hei ra pea mo tona matenga. Ko te mea pea i mate ia i te Siege o Zutphen i te 1586, i muri i tana whanaunga, a Robert Dudley, 1st Earl o Leicester, ko ia te tino tangata i taua pakanga, i mate ai te tuahine o Leicester a Sir Philip Sidney.
