The Secretary of State to the Ambassador in Germany (Wilson)
57. Vienna’s May 3, 11 a.m., concerning Heller. If you have not already done so, you should at once seek a personal interview with the Acting Foreign Minister and formally request assurances that attacks on American citizens in Vienna will cease and the necessary instructions to this end will be issued to the competent authorities immediately, and that those identified as responsible for the attacks on Heller be promptly punished.
We feel that the evidence unequivocally fixes the identity of the guilty parties and that further delay in their punishment is indefensible and calculated to invite a repetition of unwarranted attacks. You may orally request a written reply.
Please cable the result of your interview.
