In the second part of May, Klapka was designated to elaborate the united operation plan of all the armies from Hungary. According to this operation plan the main army under Görgei had to defend the Western border, while the army of Transylvania under Józef Bem had to defend mountain passes in the Eastern Carpathians, but in the same time he had to crush also the Romanian revolt from the Western Carpathians, to take the fortresses of Gyulafehérvár and Déva, then to attack towards West, taking the Titel Plateau, liberating Pétervárad, then advancing to the Adriatic Sea, or to the Western front. Although it was accepted by the Ministry Council from 20 May, this operation plan was met with harsh critics from Görgei and Bem, who accused it with no concern to the imminent Russian intervention which menaced from North and from East, and that Lieutenant General Bem and General Mór Perczel had been designated to carry out military actions which exceeded their capacities, while the other Hungarian corps were condemned to almost complete inactivity. Bem declared that he will not carry out the military actions entailed on him by this operation plan, and he will remain in Transylvania to defend it from the imminent Russian attack, while Görgei said that the only correct thing to do in this grave situation, is to immediately attack with all forces on the Western front towards Vienna, to crush the Austrian army before the Russians could intervene. As the result of these reactions and the start of the Russian intervention on 15 June 1849, the operation plan elaborated by Klapka was not carried out.
