[1] Two relatively late texts suggest that Durlabharaja was involved in a conflict with Karna, the Chaulukya king of Gujarat.
The Prabandha Kosha claims that Durlabha defeated the Gurjara king, brought him to Ajmer in chains and forced him to sell yogurt in a market.
The Hammira Mahakavya claims that Karna died in a battle against Durlabha, and lost all his wealth to the Chahamana king.
It is possible that Durlabha achieved a minor military success against Karna, which was magnified into a major victory by the later panegyrists.
[2] Hammira Mahakavya, written several years later, claims that Durlabha captured a Muslim ruler named Shahab-ud-Din, but this does not seem to be historically accurate.
