Ze'ev Jabotinsky placed Col. Robert Bitker at the head of the Irgun. Bitker had previously served as Betar commissioner in China and had military experience. A few months later, probably due to total incompatibility with the position, Jabotinsky replaced Bitker with Moshe Rosenberg. When the Peel Commission report was published a few months later, the Revisionist camp decided not to accept the commission's recommendations. Moreover, the organizations of Betar, Hatzohar and the Irgun began to increase their efforts to bring Jews to the land of Israel, illegally. This Aliyah was known as the עליית אף על פי "Af Al Pi (Nevertheless) Aliyah". As opposed to this position, the Jewish Agency began acting on behalf of the Zionist interest on the political front, and continued the policy of restraint. From this point onwards the differences between the Haganah and the Irgun were much more obvious.
