János Móga, left the camp, returned to Pest, and then left for Vienna. After crossing the Mura River Jelačić modified his earlier war plans. Overestimating the success of his advances he declined to wait for Roth’s army corps, which were scheduled to move on September 17. Therefore Roth was unable to make contact with the main forces of the Ban before September 20-21. Supply difficulties also affected his decision. Roth was instructed that his troops should not go towards Légrád, but rather take a direct northern route from Verőce across Baranya and Tolna counties towards Székesfehérvár. Jelačić hoped that the 1st (John) Dragoon Regiment would join Roth’s troops since they did not have any kind of a cavalry. Jelačić also hoped that the Schwarzenberg lancer (uhlan) regiment, withdrawn from the Banat (Bánság), would join him as well. He himself launched two of his army corps along the southern side of the Lake Balaton and the third one towards Székesfehérvár via the Iharosberény-Böhönye-Tard-Kaposvár-Simontornya route. This way he hoped to overtake the Hungarian forces at Székesfehérvár or to contact Roth’s forces in the Tolna county area. He gave up on the latter idea when he learned that the Hungarian troops were ready to evacuate Székesfehérvár. After the Croat invasion Csány had declared a levée en masse within the threatened counties and Batthyány expanded it onto the whole of Transdanubia on September 19. The levy became more active because a substantial part of the Croat army started looting immediately after crossing the Hungarian borders. Although their destructiveness could not be compared with the atrocities committed by the Serbian rebels, their looting was a deep source of bitterness for the people of Transdanubia. This is why it was evident that Batthyány’s call for levy in mass met with such a good response. Jelačić himself had not counted on that either. Ten days after the Croat troops crossed the Dráva River, communications between the army and the hinterland practically ceased to exist. The Zala and Somogy county national guardsmen, militiamen, and volunteers intercepted several hundred carriages transporting food and equipment, thus preventing the Croatian troops left behind from venturing beyond Nagykanizsa. During a surprise attack a major part of Jelačić's mail came into Hungarian hands. It turned out from the intercepted letters, some of which were published in the official journal, that Jelačić was tightly connected with the Austrian government and that Minister of Defense
