Kommandant Louw commanded his own commando in north west Cape Colony. Known actions include Tontelboschkolk, Middelport, Windhoek, Ookiep and Springbok.
He was involved in the murder of the coloured spy, Abraham Esau. Worsfold notes:
It was at this time that the utterly unjustifiable and brutal murder of the coloured man, Esau, took place in the invasion of the Calvinia district of the Cape Colony. His sole offence was his known loyalty to the British Government. "He was flogged on January 15th, 1901, and kept in gaol till February 5th, when he was flogged through the streets and shot outside the village by a Boer named Strydom, who stated that he acted according to orders.
