A night interrupted by Ribbentrop’s restiveness [Ciano began his diary on December 5]. After having delayed two days he now hasn’t a minute to lose in answering the Japanese, and at 3 o’clock in the morning he sends [Ambassador] Mackensen to my house to submit a plan for a Tripartite Pact of Japanese intervention and the promise not to make a separate peace. They wanted me to wake up the Duce, but I did not do it, and the Duce was very pleased.
