The nuclear age
In July 1945 the Pacific War was still raging, with the allied powers fighting the Empire of Japan. The US had developed a new, terrible weapon which gave it the capacity to end this dreadful war.
On 16 July the first test of an atomic bomb, codenamed ‘Trinity’, was carried out in New Mexico.
On 6 August, a uranium atomic bomb was dropped on Hiroshima, which devastated the Japanese city and instantly killed around 80,000 people (many more were to die from burns and radiation sickness).
After a second atomic bomb was dropped on Nagasaki on 9 August, Japan surrendered on 15 August.
