Tuhia he tomokanga mō tēnei wāhanga - I rere a Dorey ki Cuba i te marama o Paenga-whāwhā 1898 i te wā o te Pakanga Paniora-Amerika, ā, i uru ki te Pakanga o El Caney
me te Siege o Santiago i te Hōngongoi o taua tau. I muri mai ka uru atu ia ki te Pakanga o Philippine-American me te mahi hei Kaitautoko o te 4th Infantry Regiment i nga mahi whawhai ki a Moros i Zamboanga me Manila. I whakahaua e Dorey hei Kapene i te roopu o nga Kaitiaki o Philippines i Mindanao a ka tohua hei Aide-de-Camp ki a Major General Leonard Wood, nana nei i mahi hei kawana o te Rohe o Moro, he pa kaha o te tutu Muslim. I whakawhiwhia a Dorey ki tana whetu hiriwa tuatahi mo tana maia i Philippines.
