Vice Admiral Jean Decoux, who commanded the French naval forces in the Far East, and was based in Saigon. Decoux and Catroux were in general agreement about policy, and considered managing Nishimura the first priority. Decoux had additional worries. The senior British admiral in the area, on the way from Hong Kong to Singapore, visited Decoux and told him that he might be ordered to sink Decoux's flagship, with the implicit suggestion that Decoux could save his ships by taking them to Singapore, which appalled Decoux. While the British had not yet attacked French ships that would not go to the side of the Allies, that would happen at Mers-el-Kébir in North Africa within two weeks; it is not known if that was suggested to, or suspected by, Decoux. Deliberately delaying, Decoux did not arrive in Hanoi until July 20, while Catroux stalled Nishimura on basing negotiations, also asking for U.S. help.
