In these bombardments 3 kanme (unit of weight) of ozutsu made in Kunitomo were used, and probably four culverins imported from England about in June, one Saker and 4.5 kanme of 12 Dutch cannons that had arrived in Hyogo Port seven days before were included.
この砲撃では国友製3貫目の大砲が用いられており、また6月頃にイギリスより購入したカルバリン砲4門、セーカー砲1門や7日前に兵庫港に到着したオランダ製4・5貫目の大砲12門も含まれていると思われる。
