Washington. Kazuji Kameyama, the cable chief, broke it into fourteen
approximately equal parts to facilitate handling and ordered these
enciphered on the 97-shiki O-bun In-ji-ki. He also enciphered a shorter
"pilot" message from Togo alerting the embassy that the reply was on the
way and instructing it "to put it in nicely drafted form and make every
preparation to present it to the Americans just as soon as you receive
instructions." At 8:30 p.m., the pilot message was telegraphed from the
cable room to Tokyo's Central Telegraph Office, from where, 45 minutes
later, it was radioed to the United States. Bainbridge Island intercepted it
and relayed it to OP-20-G. By five minutes past noon on Saturday,
December 6 (Washington time), OP-20-o had delivered the teletype copy
to S.I.S., which promptly ran it through the PURPLE machine. By 2 p.m.
Bratton had it, translated and typed. An hour later it was in the hands of
the Army distributees. S.I.S. had officially closed at 1 p.m
