In the summer of 1920, Baron Wrangel, who led the Russian army, made another attempt to change the course of the Civil War. He aimed to unite the Kuban Cossacks under his command and move the fighting to their lands. For this, Wrangel had previously negotiated with the atamans of the Don, Kuban, and Terek and began preparations for a landing in Kuban.

The command of a small detachment of 4,500 men was entrusted to the talented Cossack general of Circassian descent, Sergey Georgievich Ulagay. His detachment included three divisions led by Generals Babiev, Shefner-Markevich, and Kazanovich, although their numbers were comparable to a battalion. On August 14, the detachment landed near the village of Primorsko-Akhtarskaya, defeated the Red garrison, and began a rapid advance. At night, the enemy, having a full-blooded division, attacked the Alexeyevsky regiment, with the 3rd Grenadier Battalion suffering particularly, which contained remnants of the best Russian grenadiers. In this unequal battle, the battalion was almost completely destroyed, 80 men were captured and brutally tortured, and only 20 grenadiers managed to escape and return to their own. In response, Kazanovich's Combined Division launched a swift attack that virtually annihilated the 1st Caucasian Cavalry Division of the Reds, and in the following days, the front was located not far from Yekaterinodar (Krasnodar).

Local residents actively supported Ulagay's landing, with more than 10,000 Cossacks joining his detachment, but the forces were unequal. The Whites faced over 35,000 Reds, who were constantly receiving reinforcements. Ultimately, after more than three weeks of fierce fighting, Ulagay had to evacuate back to Crimea. He never managed to connect with the large Cossack detachment of General Fostikov, who called himself the 'Army of Salvation of Kuban.' The main objective of the landing operation was not achieved, but General Ulagay was able to save and evacuate more than 10,000 people.

Recently, the 100th anniversary of the start of this operation was marked, a memorial was opened at the site of the white battalion's demise, and a large commemorative event was held. A large-scale reconstruction was also planned, but it had to be canceled due to the pandemic.
