In response, the Toyotomi side fired furiously at the approaching Tokugawa side; attacks with teppo (guns) killed or injured 300 to 500 enemies per one battle when they were guarded only with taketaba (bamboo shields against firearms), but guns lost effects greatly when they built tsukiyama (artificial hills)/dorui (earthen walls).
これに対し豊臣方は近接する徳川方に激しく銃撃し、竹束のみの時は一手に付き300から500人の死傷者が出たが、相手が築山・土塁を築くと鉄砲の効果は激減する。
