Whakaotihia te rerenga e whai ake nei: I Ingarangi a Williams ki te āwhina i te whawhai ki te Armada Paniora i te tau 1588. I haere tahi a Williams ki a Sir Francis Drake i
te haerenga ki Spain me Portugal i te tau 1589, kātahi ka whawhai i runga i te ingoa o ngā Huguenots French. I tutaki ia ki te Earl o Essex i te 1589, a ka piri te tokorua i te wa i tonoa ai raua e Kuini Erihapeti ki te arahi i tetahi ope hei hoa o Henry o Navarre ki te Rōpū Katorika i te wa o te noho a Spain ki Brittany i te 1592. I haere ia ki te mahi ki a Henry ki te Rōpū i te mutunga o nga tau 1580 me nga tau 1590, i wikitoria i te wikitoria nui i te Pakanga o Arques. Whai muri i te hokinga mai o Essex ki Ingarangi, ko Williams te rangatira o nga ope Ingarihi e tautoko ana i a Henry me te "de facto" i tono mai i te Kuini. I muri tata mai ka mau ia ki a Aumerle me nga tangata 600 anake. I te whakapae o Rouen i te tau 1592, tata ana ia ki te patu i te kaiarahi Albanian-Itariana a Giorgio Basta i roto i te whawhai whaiaro, ka tapahia tona kaki ka peia ia me ana tangata mai i te parae. Nā ēnei mahi i rongonui ai a Williams hei toa i Ingarangi, ā, ka whakaputaina ngā pukapuka o ana mahi. I kii a Sir Henry Umton he nui te whakamoemiti a Kingi Henare mo Williams me ana tangata, "Kaore au i rongo i a ia e whakanui ana i tetahi ratonga, i tetahi tangata ranei i tana ki a Sir Roger Williams me era atu".
