That was Hiroshima. Although there was a high number of civilian casualties it was actually chosen on the basis of its importance to the Japanese imperial army, both as a base and an industrialized city. >Hiroshima was a supply and logistics base for the Japanese military.[117] The city was a communications center, a key port for shipping, and an assembly area for troops.[78] It supported a large war industry, manufacturing parts for planes and boats, for bombs, rifles, and handguns.[118] Source: https://en.m.wikipedia.org/wiki/Atomic_bombings_of_Hiroshima_and_Nagasaki https://en.m.wikipedia.org/wiki/Atomic_bombings_of_Hiroshima...
