14 January 1904
The post offices at Waldau and the Waterberg in German South West Africa (now Namibia) were destroyed during the Herero Revolt. Violence also erupted at Omarasa, north of the Waterberg. The Ovaherero conquered the Waterberg military station. All soldiers under the command of Sergeant G. Rademacher were killed. Samuel Maharero allowed missionary Eich with his small party of German women and children safe passage from Waterberg to Okahandja, SWA. At the time Namibia was still a German colony.
