Whilst making their way towards Urga across the Gobi Desert, the French Citreon Kegresse expedition found their way blocked by the army of Chinese Warlord Wei Phat Mac.

Unable to negotiate a peaceful solution to allow them to pass, the Expedition attacked this army to force passage. The Chinese bravely advanced to challenge the Expedition only to suffer heavy casualties due to moving slowly during their advance due to the failure of Wei Phat Mac to throw decent movement dice. Exposed in open terrain, the Chinese infantry were mowed down by the French machine guns on the Kegresses, Laffey White Armoured car and heavy machine gun of the Foreign Legion escort.

Both the Chinese field gun and the French Mountain gun failed to be effective as the Chinese armoured car attempted to support the infantry advance. A lucky shot from this latter armoured car

took out one of the Kegresses, but it in turn was knocked out by a shot from the Laffey White.

Having hid behind a hill for most of the battle, the Chinese irregular cavalry made one last bid to change the course of the battle as the raced to take out the French Heavy Machine gun, only to get caught in a fire of the Foreign Legion and the remaining Kregresse.

The Chinese close order infantry managed to close with French Colonial scouts as did the Chinese Bandits, inflicting minor casualties. With loss mounting and without having committed his personal guard, Wei Phat Mac withdrew from the field, allowing the Expedition to continue its advance towards Urga.
