Liebenberg participated with his Griqualand troops in the lost Battle of Diamond Hill (Slag van Donkerhoek), where Louis Botha ordered a retreat to Bronkhorstspruit on 12 June 1900. When president Kruger requested general De la Rey to start another invasion of the Cape Colony, he acquiesced on 2 July 1900 and would be accompanied by the generals Liebenberg, Du Toit, Snyman and Douthwaite for their strong resistance at Donkerhoek. Enthused by the Boer victory at Silikaatsnek (Silkaatsnek) near Hartbeespoort west of Pretoria on 11 July 1900 after months of defeats, Boer volunteers enlisted from West Transvaal. General De la Rey sent Liebenberg with a Krupp cannon and a pom-pom to command the Potchefstroom Commando on 14 July 1900. Generals Christiaan De Wet and Liebenberg combined their forces to a total of 1500 men and laid a siege around Frederikstad on 20 October 1900 but had to flee after five days when British reinforcements under Lt.-Col. H. T. Hicks arrived.
