Alexey Danilovich Bezkrvny was a descendant of the Zaporozhian Cossacks. In 1792, his ancestors moved to Kuban along with the Black Sea Army. His father, a senior officer of this army, owned a family estate in the village of Shcherbinovskoye.

Alexey received his education at home. He mastered Russian literacy and part of Russian arithmetic.

In 1800, Bezkrvny entered military service as a simple Cossack of the Black Sea Army. He participated in the Zakuban campaigns against the mountaineers. In 1803, he became a sotnik (captain), and in 1808, for his bravery, he was promoted to khorunzhy (ensign).

During a battle with the mountaineers on the Ilyederka River on March 11, 1810, he received a severe wound to his left shoulder.

In 1811, he was transferred to the newly formed Separate Black Sea Hundred, which became part of the Life Guards Cossack Regiment.

Bezkrvny participated in the Patriotic War of 1812. As part of the guard, he fought in rearguard battles. Commanding the Black Sea Guard Officer Hundred, he distinguished himself in the Battle of Borodino, where, despite heavy grapeshot fire, he attacked a French battery and captured two officers and nine soldiers. During the attack, his horse was killed under him, and he himself was wounded in the left leg. On August 28, 1812, his hundred repelled enemy attacks.

Bezkrvny fought successfully in other battles, pursuing the retreating troops of Napoleon. For his bravery, he was awarded golden weapons. By the end of 1812, he had proven himself to be a brave and tactically skilled commander.

In 1813, for outstanding bravery, he was appointed to the convoy of Emperor Alexander I. As part of the convoy, he participated in battles near Bautzen and other major fights.

For his successes in military service, he received the ranks of staff rotmistr (captain) and rotmistr, and his hundred received silver trumpets. During the foreign campaigns of the Russian army in 1813 and 1815, he was wounded in battles near Kulm and Leipzig.

By the highest decree, he was transferred from the Life Guards to the Black Sea Army with the rank of lieutenant colonel.

On April 20, 1818, for his bravery in the Battle of Nations, he received the rank of colonel and the Order of St. Vladimir 4th class.

Returning to Kuban, Colonel Bezkrvny commanded the 9th Cossack Regiment and participated in the Zakuban expeditions against the mountaineers. For his diligence and bravery, he was awarded a sum of 5,000 rubles and a diamond ring.

On May 6, 1823, he was appointed commissioner of the 3rd Cavalry Regiment, with which he remained in the Kingdom of Poland until November 1826, guarding the border with Prussia. For decisive actions in extinguishing a fire in Mlava, he received gratitude from Grand Duke Konstantin Pavlovich and the Order of St. Anna 2nd class.

On March 21, 1827, his regiment returned to the Black Sea region.

On September 27, 1827, Bezkrvny became the military ataman of the Black Sea Army and commanded the Black Sea border line. In the same year, he was renamed to the acting ataman.

During the Russo-Turkish War of 1828-1829, he commanded the Taman detachment, consisting of Cossacks and regular troops. He distinguished himself during the capture of the fortress of Anapa, where he commanded the advance detachments. For his successful actions, he was promoted to major general and awarded the Order of St. George 4th class. The regiments of the Black Sea Army were granted banners.

In 1829-1830, he conducted successful expeditions against the mountaineers, for which he received a golden saber with diamonds and the inscription 'For Bravery.' In early 1830, he repelled a raid by the mountaineers, and on January 30, his detachment entered the lands of the Shapsugs, where he personally participated in hand-to-hand combat and received three wounds. In the same year, by his order, three fortifications were built on the Kuban, one of which was named Alexeyevskoye in his honor.

However, he was soon accused of abuses, and in November 1830, he was dismissed from the position of ataman of the Black Sea Army.

In the last years of his life, he was under trial, fell seriously ill, and died on June 9, 1833, at the age of 48. He was buried in the Sorrowful Church in Krasnodar.

Before his death, he bequeathed funds for the construction of a shelter for Cossacks and transferred timber to the city of Ekaterinodar on the left bank of the Karasun River.

In the Conduit list of the ataman, it is indicated that over 30 years of service, he participated in 14 campaigns and more than 100 battles. A portrait of Bezkrvny has not survived, but contemporaries remembered him as a man of immense physical strength, tall, with a handsome and manly face, possessing unique military abilities and a keen mind.
