After escaping from German custody Shukhevych once again headed the military section of the OUN.
In May he became a member of the leadership of the OUN and in time the head.
In August 1943 at the Third Special Congress of the OUN, he was elected head of the Direction of the OUN and Supreme Commander of the Ukrainian Insurgent Army known as UPA.

Under Shukhevych's leadership the evolution of the program for which the OUN fought was further refined.
Its core tenets were:
Opposition to all forms of totalitarian government
Construction of a democratic state system in Ukraine
Guaranteed right for self-determination against empire and imperialism.

According to Ukrainian historian and former UPA soldier Lev Shankovsky, immediately upon assuming the position of commander of UPA Shukhevych issued an order banning participation in anti-Jewish activities.
No written record of this order, however, has been found.

The Insurgent Army was joined by various people from the Caucasus and Central Asia who had fought in German formations.
The rise of non-Ukrainians in the Ukrainian Insurgent Army gave stimulus to the special conference for Captive Nations of Europe and Asia which took place November 21–22, 1943 in Buderazh, not far from Rivne.
The agenda included the formation of a unified plan for the attack against occupational forces.

During the period of German occupation Shukhevych spent most of his time fighting in the forests, and from August 1944, following Ukraine's annexation by the Soviet Army, he lived in various villages in Western Ukraine.
In order to unite all Ukrainian national forces to fight for Ukrainian independence, Shukhevych organized a meeting between all the Ukrainian political parties.
As a result, the Ukrainian Supreme Liberation Council (UHVR) was formed.
