I muri i te pakanga, ka hinga te Marine Corps ki roto i te raruraru i mutu me te whakatuunga o Archibald Henderson hei Kaiwhakahaere tuarima i te tau 1820. I raro i tana mahi, ka riro i te Corps nga mahi whakatere i te Karipiana, te Gulf of Mexico, Key West, West Africa, nga Falkland Islands, me Sumatra. Ka whakawhiwhia a Commandant Henderson ki te whakakahore i nga ngana a te Perehitini Jackson ki te whakakotahi me te whakauru i te Marine Corps ki te ope taua. Engari, i paahitia e te Kaunihera te Ture mo te Whakahaere Pai o te Marine Corps i te 1834, e kii ana ko te Corps tetahi waahanga o te Tari o te Navy hei tuahine ki te ratonga Navy. Koinei te tuatahi o nga wa motuhake i whakawakia ai te noho o te Corps.
