During his service as the commander in chief of the Uprising, Dowbor-Muśnicki was responsible for almost complete reorganization of what was started as a para-military partisan force. He introduced conscription and mobilized eleven classes of recruits and reformed the partisans into divisions. During his command, the Greater Polish Army grew from merely 20,000 to over 100,000 soldiers, well-armed and well-equipped. After the Battle of Ławica in which the Poles managed to capture the airfield, the Greater Polish Army was the fourth force in the world in number of aeroplanes available. Dowbor-Muśnicki focused also on political matters and strived for political neutrality of the forces under his command, which made him demobilize some of the leftist and rightist officers. He also disbanded the leftist "soldiers' councils".
