The battle called the Battle of Fujito was also described in the "Heike Monogatari (The tale of the Heike)," and according to the Heike Monogatari, Moritsuna, who got information from a fisherman about a ford which was shallow enough for horses to cross, rode across the sea by cutting through the waves and took the lead in invading an island to which Yukimori confined himself.
この合戦は藤戸合戦と呼ばれ、『平家物語』にも描かれており、島に篭もる行盛に対し、漁師から馬でも渡れる浅瀬を聞き出した盛綱が、波を馬で乗り越え先陣を切って攻め入ったとされる。
