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. On the other hand, overall morale amongst the members of the brigade was very high. 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
Zboriv (Czech and Slovak: Zborov) 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 ==
