Ottoman held Iraq seemed a peculiar choice for Nader's invasion as all the western territories of Persia were restored under the ignominious treaty signed by Tahmasp with the Caucasus under Turkish control.

To achieve a modicum of surprise Nader decided upon a march through the mountains as opposed to a direct advance against the fortified border town of Zohab near Qasr-e Shirin.

The mountain path was a difficult and snowy route to negotiate and some amongst the soldiers perished but Nader managed to get his 600 men to descend down into the valley behind the Ottoman battlements and without hesitation struck in the dead of night.

Making an almost fantastical recovery from his seemingly irreplaceable losses Nader rebuilt his army in an incredibly short amount of time and invaded Ottoman Iraq once more.

An intense musketry duel was kept up along the entire breadth of the line until Nader ordered his infantry to unsheathe their sabers and charge the Ottomans, supporting them with a pincer movement by his cavalry reserve which put Topal Osman's army in a cauldron of Persian troops.
