Tuhia he tomokanga mō tēnei wāhanga - I tae mai tōna tuakana a Georg ki Cape Town i te marama o Mei 1834 ā, i whakawhiwhia ki a ia he raihana hauora, ka uru atu ki ētahi atu mema o te whānau ki "Lichtenstein" i te marama o Hūrae. He nui te mahi i hangaia ki te pāmu i muri i te Pakanga Ono o Kaffir
o te tau 1834/5. Ka ora tonu ngā reta a Krebs mō te pakanga. I whakatuhia e Georg tetahi mahi i Graaff-Reinet, i muri mai ka noho hei Kaihautū Rohe. I mate te hoa o Krebs a Leopold Scmidt i te Hōngongoi 1836 a ka whakakorea e Krebs ana paanga katoa ki Grahamstown, engari i haere tonu ia ki te wehe atu i te pāmu.
