Germans in a camp, overheard a drunken conversation about their planned attack against the Basters. She took the word to the Kaptein, and around 700 Basters retreated to Sam Khubis south-east of Rehoboth in the mountains, to prepare for German attack. This group included women and children. Van Wyk had hidden his wife and children at farm Garies, along with the wives and children of Stoffel and Willem van Wyk. Stoffel's wife, two children, an adult daughter of Cornelius van Wyk, and his 18-year-old son, were all killed there. The others, including van Wyk's wife Sara, were taken to Leutwein station and released on May 13. On 8 May 1915, the Germans attacked in the Battle of Sam Khubis, where the stronghold was defended by 700 to 800 Basters. Despite repeated attacks and the use of two cannons and three Maxim machine-guns, the Germans were unable to destroy the Basters' position. They ended the attack at sunset. At the end of the day, Basters had all but run out of ammunition and expected defeat. That night they appealed to God, pledging to commemorate the day forever should they be spared. Their prayer is engraved on a memorial plaque they later installed at Sam Khubis and reads: God van ons vaderen / sterke en machtige God / heilig is Uw naam op die ganse aarde / Uw die de hemelen geschapen heft / neigt Uw oor tot ons / luister na die smekingen van Uwe kinderen / de dood staart ons in het gesicht / die kinderen der bose zoeken onze levens / Red ons uit die hand van onze vijanden / en beskermt onze vrouen en kinderen / En dit zult vier ons en onze nacheschlacht zijn een dag als een Zondag / waarop wij Uw naam prijzen en Uw goedertierenheid tot in euwigheid niet vergeten "God our father / strong and powerful / holy be Thy name all over the earth / Thou that made heaven / bow Thou down to us / listen to the cries of Thy children / death stares us in the face / the children of evil seek our lives / Save us from the hand of our enemies / and protect our wives and children / and this shall be for us and our kin a day like a Sunday / on which we shall praise Thy name / and Thy gratitude shall
