Item 03 : General William Holmes Papers regarding capitulation, September-October 1914 - Page 143
Dear Col. Wallack;
This will serve to introduce to you, Herr Wilhelm Wostrack, German Resident Commissioner of Nauru, who was taken Prisoner by me along with twenty-five (25) others on 6th instant.
Herr Wostrack has been on parole since leaving Nauru, and I trust, in view of the high office he held and the assistance he has given me, that the same consideration may be extended to him by you on his arrival in Sydney. He is accompanied also by his Wife.
With kindest regards.
Colonel E.T. Wallack, C.B.
