During World War I, combat operations were conducted not only in Europe. Significant forces were concentrated in the Caucasus, and Russia also paid attention to Persia, the central part of which was effectively controlled by the Germans. Together with the Turks, they sought to use this region to gain access to oil, but the English were thwarting their plans. In support of the allies, the Russian General Staff decided to send a Cossack hundred, led by Kuban Cossack Vasily Danilovich Gamaliy. Their goal was a raid into the Turkish rear and to connect with the English.

Problems began immediately after crossing the border. The Cossacks were pursued by bandit gangs, shot at during the night, and pelted with stones from the mountains. Difficulties also arose with guides, who often deceived the Cossacks. Once, an Arab guide tried to lead them into the desert, but after 50 versts, the cavalrymen realized the deception. Under the threat of weapons, the guide confessed to his intentions.

The Cossacks had to resort to cunning. One day, Vasily Gamaliy noticed a large armed tribe ahead. To avoid a confrontation, he and his assistant approached them and, pretending that their detachment was the advance guard of the main body, entered into negotiations. The tribe's leaders believed them and allowed the Cossacks to pass.

On May 19, 1916, overcoming all difficulties, the Russian warriors met with the English. Their appearance made a strong impression. The English expressed their gratitude and awarded the Cossacks. In Russia, they also became heroes: the entire hundred received George crosses for the raid into enemy territory. After the revolution, Vasily Gamaliy joined the Whites and later emigrated to the USA, where he died in 1956.
