On the day after the Hiroshima strike, General Farrell received
instructions from the War Department to engage in a propaganda campaign
against the Japanese Empire in connection with the new weapon and its
use against Hiroshima. The campaign was to include leaflets and any
other propaganda considered appropriate. With the fullest cooperation
from CINCPAC of the Navy and the United States Strategic Air Forces, he
initiated promptly a campaign which included the preparation and
distribution of leaflets, broadcasting via short wave every 15 minutes
over radio Saipan and the printing at Saipan and distribution over the
Empire of a Japanese language newspaper which included the description
and photographs of the Hiroshima strike.
The campaign proposed:
1. Dropping 16,000,000 leaflets in a period of 9 days on 47 Japanese
cities with population of over 100,000. These cities represented more
than 40% of the total population.
