I whakaingoatia a Doyle hei Knight of Grace o te Order of the Hospital of Saint John of Jerusalem i te tau 1903. He kaitautoko a Doyle mo te pakanga mo te whakahou i te Kawanatanga Koreutu o Kongo, na te kairipoata a ED Morel me te kaitono a Roger Casement. I te tau 1909 i tuhia e ia Te hara o te Congo, he pukapuka roa i whakahe ai ia i nga whakamataku o taua koroni. I mohio ia ki a Morel me Casement, ana pea, i uru tahi me Bertram Fletcher Robinson, i whakaaweawe i etahi tohu i roto i te pukapuka The Lost World i te tau 1912. I pakaru a Doyle ki a Robinson i a ia e noho ana hei kaiarahi o te nekehanga pacifist o te Easter i te Pakanga Tuatahi o te Ao. I te wa i kitea ai a Doyle he hara mo tana mahi, kaore i taea te whakaora i a ia i muri i te mate o te Karauna: Ko wai i kaha ki te whakahe i a Casement i te wa o te Pakanga Tuatahi o te Ao?
