Eventually, the three independent commands of Generals McDowell, John C. Frémont, and Nathaniel P. Banks were combined into Major General John Pope's Army of Virginia and McDowell led the III Corps of that army. Because of his actions at Cedar Mountain, McDowell was eventually brevetted major general in the regular army; however, he was blamed for the subsequent disaster at Second Bull Run. McDowell was also widely despised by his own troops who believed him to be in cahoots with the enemy. He escaped culpability by testifying against Major General Fitz John Porter, whom Pope court-martialed for alleged insubordination in that battle. Pope and McDowell did not like each other, but McDowell tolerated serving under him with the full knowledge that he himself would remain a general after the war was over while Pope would revert to the rank of colonel. Despite his formal escape, McDowell received no new assignments for the next two years.
