Less than one and a half kilometres from the hypercenter, Shukkeien, laid out on the instructions of the Lord of Hirohsima 326 years previously, was almost completely levelled by the blast and resulting fires. The rainbow bridge spanning the centre of the pond, modelled, like the rest of the garden, on Hangzhou's West Lake, was the only structure to remain intact. Thousands of survivors sought refuge here after the bomb. Most died before they could receive medical attention.
It was very crowded, and to distinguish the living from the dead was not easy, for most of the people lay still, with their eyes open...The hurt ones were quiet; no-one wept, much less screamed in pain; no-one complained; none of the many who died did so noisily.
