砲・構造物と防禦システム

抄録

Foreign ships came into the territorial seas in the late Edo period forced the shogunate to revitalize the plan of defending the country. Defending with cannons was planned as a strategic choice and manufacturing of cannons was promoted in that period. Material processing especially under manufacturing of cannons has already been researched. Cannons require structures for their deployment, which were mainly batteries called Daiba. They were constructed on the sea and by the seashore all over the country. This series of research mainly focuses on material processing under manufacturing related to coastal defence. Cannons and batteries are generally deployed in an integrated plan, so how they were deployed relatedly composes another important issue. Defending by firing also requires defending against firing and supplying for firing, components for which also had to be deployed between multiple cannons on batteries. The aim of this paper is to research cannons, structures and defence system.
