may be considered his error. In the Battle of Isaszeg from 6 April, the first decisive battle of the Spring Campaign, after initial successes, Klapka's I Corps were pushed back by Jelačić's superior forces, which made Klapka waver, and to think seriously to retreat from the battlefield, letting Damjanich's III Corps alone, but the arrival of Görgei, and his order to resist at all costs, then the arrival of the II Corps led by Lajos Aulich, convinced him to remain and fight. At the end of the battle Klapka's I corps charge chased the enemy from Isaszeg and brought the victory for the Hungarians. The fluctuating behavior of Klapka during the battle showed that despite of being a good strategist, creating good operation plans, which enabled, in the Spring Campaign, to defeat the superior imperial troops (55,000 Austrians against 47,500 Hungarians), he could be hesitating in their execution.

But in the other battles of this phase of the Spring campaign Klapka distinguished himself. In the Battle of Nagysalló (19 April), he played a leading role in that victory, in the same way as in the relief of Komárom (26 April). In the middle of April he received the 2nd Class Hungarian Military Decoration. At 30 April 1849 he was named deputy War Minister substituting Görgei, who was leading the Siege of
