For the U.S. and its allies, the victory in the Tenaru battle was psychologically significant in that Allied soldiers, after a series of defeats by Japanese Army units throughout the Pacific and east Asia, now knew that they could defeat the Imperial Armies in a land battle.
Bagi Amerika Serikat dan sekutu-sekutunya, kemenangan di pertempuran Tenaru adalah penting secara psikologis dalam hal bahwa serdau-serdadu Sekutu, setelah kekalahan beruntun terhadap kesatuan-kesatuan Angkatan Darat Kekaisaran Jepang di seluruh Pasifik dan Asia Timur, sekarang tahu bahwa mereka bisa mengalahkan pasukan Jepang dalam pertempuran darat.
