According to "Hachiman Gudokun," in the middle of the battle, a fire started, probably from firearms, in Hakozaki-gu Shrine, where warriors of the Kamakura shogunate decided as their base for interception and prayed for the gods' help, and it burned down the main building of the shrine, but they managed to save goshintai (object of worship believed to contain the spirit of a god) and other materials by carrying them out in a chest.
『八幡愚童訓』によると、この戦いの最中、鎌倉武士団が迎撃の拠点として加護を祈った筥崎宮から兵火によるものか出火し、社殿は焼け落ちたものの御神体その他は唐櫃に納めて運び出し、辛くも避難出来たという。
