For the first story, the British obtained the coded text of the telegram from the Mexican commercial telegraph office. The British knew that since the German embassy in Washington would relay the message by commercial telegraph, the Mexican telegraph office would have the coded text. "Mr. H", a British agent in Mexico, bribed an employee of the commercial telegraph company for a copy of the message. Sir Thomas Hohler, the British ambassador in Mexico, later claimed to have been "Mr. H" or at least to have been involved with the interception in his autobiography.[27] The coded text could then be shown to the Americans without embarrassment.
