The Battle of Zborov (Зборівська битва, Zborivska bytva in Ukrainian, Зборовское сражение in Russian, Schlacht bei Zborów in German, bitva u Zborova in Czech, bitka pri Zborove in Slovak) was a part of the Kerensky Offensive (the last Russian offensive in World War I, taking place in July 1917). The battle was the first significant action of the Czechoslovak Legions (volunteers fighting against the Central Powers) on the Eastern Front and the only successful engagement of the failed Russian offensive.

Background

As the reliability of many Russian military formations was in doubt, only units that volunteered to attack were used in the offensive. Among those who did was the Czechoslovak Riflemen Brigade (Československá střelecká brigáda), often called the Czechoslovak Legion, formed from three regiments of Czechs and Slovaks. The brigade (about 3,530 men), was low on equipment and training. Moreover, this was the first use of the brigade as a single formation; previously, the Russian command had used only smaller units of the brigade, mostly in reconnaissance actions.^[4] On the other hand, overall morale amongst the members of the brigade was very high.^[1]

The brigade was commanded by Russian Colonel Vyacheslav Platonovich Troyanov, but the tactical assault plan was prepared by Czech and Slovak officers serving in the Czechoslovak Legion. Professor Tomáš Masaryk, the main organizer of the Czechoslovak resistance against Austria-Hungary, was in telegraphic connection with colonel Nikolai Petrovich Mamontov so he could follow the situation from Saint Petersburg.

The brigade was deployed near Zborov, a town in today's Ukraine, in a sector of secondary importance. The 4th division protected it from the north, the 6th division from the south. The enemy, the army of Austria-Hungary, deployed four well entrenched and well equipped infantry regiments (IR), the IR 6, 35, 75 and 86 (in all, about 12,000 men).

Battle

At 5:15 on the 2 July, the second day of the offensive, after an initial artillery bombardment, small groups of Legionnaires equipped with grenades attacked the enemy. At 8:00, Colonel Mamontov called Lieutenant Stanislav Čeček by phone to start the attack. After shock troops breached the barbed wire defenses, follow-up units took over to continue the attack. By 15:00 the Legion had advanced deep into enemy territory, breaking through the entire Austrian trench line; 3,300 enemy soldiers (62 officers) were captured, while 20 guns and large amounts of war material were seized.^[5] The Legion's losses were 167 killed, 17 mortally wounded, 11 missing and around 700 injured.

Aftermath

This success had no wider effect on the doomed offensive. The battle, however, gave propaganda and political capital to the leaders of the Czechoslovak resistance and convinced the Russian government to end its limitations on new units formed from Czech and Slovak soldiers captured during the war. Moreover, news of the armed action of the Czech exterior resistance reached the Czech people in Austria-Hungary for the first time. Any reference to Czech volunteers fighting on the side of the Entente was suppressed by censorship. But the surprising victory by the smaller Czechoslovak forces incited some Austrian politicians to demand an investigation of alleged treason by Czech units in the Austro-Hungarian Army and this made the victorious legionaries famous across the Empire.

After the war, the battle was used to propagate the heroic military cult surrounding the Legions who formed a cornerstone of the new Czechoslovak state. During the German occupation of Czechoslovakia (1939-1945), and later, when the communist party took power in 1948, the story was suppressed or ignored.

In the arts

The battle was depicted in the 1938 Czech language propaganda film Zborov. The movie was based on a story by Rudolf Medek and directed by Jiří Slavíček and Jan Alfréd Holman. Due to the Munich Agreement, a shortened version of Zborov was first screened in January 1939.
