Whakakīhia te rerenga e whai ake nei: I whakahau ia i te kaipuke kaipuke i roto i te North Atlantic Blockading Squadron i te tau 1864<unk>65, me te wehenga o te Admiral Porter's Squadron i nga pakanga e rua o Fort Fisher i te marama o Tihema 1864 me
Hānuere 1865. Katahi ka tohua a Thatcher hei rangatira mo te Western Gulf Squadron, ka tiimata tonu nga mahi i te mahi tahi me te General Canby, rangatira o te ope taua o West Mississippi, i te hopu i Mobile, Alabama. I muri i te pupuhi poto me te kaha, i mau a Spanish Fort me Fort Blakeley i te ope a te Uniana i te 9 o Aperira 1865. I te ngaro o nga paruru matua o te taone, ka wehe atu nga hoia o te Rōpū ki Mobile i te Paenga-whāwhā 12. I tono a General Granger me te Kaitohutohu o te Admiral Thatcher kia tukua te pa, a ka riro te pa.
