General Andrew Jackson commanded the US Army in the Battle of New Orleans in 1815. It actually occurred 2 weeks after the British signed a peace treaty ending the War of 1812, but communications were so slow back then, no body knew. Jackson later became president
No. George Washington was, as the first US president in 1789. Washington had previously been the "commander" and "general-in-chief" of the Continental Army from 1775 to 1783 during the American Revolution.

The US Sixth Army was commanded by Walter Krueger during all its combat operations. Krueger was the first soldier to rise from private to general in the US Army. He was born in eastern Germany (now Poland) and immigrated with his family to the US when he was eight.

Colonel Leonard Wood, a Regular US Army Officer, commanded the "Rough Riders".
John J. Pershing.
Command of all US armies changed hands a few times during the war. From McClellan to Helleck to McClellan to Meade to Grant. For the Union's premier army, the Army of the Potomac, it had multiple commanders. Once again US President Lincoln seemed to do a poor job in selection commanding generals.
