[39][40]
In the spring of 1814, Taylor was called back into action under Brigadier General Benjamin Howard, and after Howard fell sick, Taylor led a 430-man expedition from St. Louis, up the Mississippi River. In the Battle of Credit Island, Taylor defeated Indian forces, but retreated after the Indians were joined by their British allies.[41] That October he supervised the construction of Fort Johnson near present-day Warsaw, Illinois, the last toehold of the U.S. Army in the upper Mississippi River Valley. Upon Howard's death a few weeks later, Taylor was ordered to abandon the fort and retreat to St. Louis. Reduced to the rank of captain when the war ended in 1815, he resigned from the army. He reentered it a year later after gaining a commission as a major.[42][43]

Command of Fort Howard
Taylor commanded Fort Howard at the Green Bay, Michigan Territory settlement for two years, then returned to Louisville and his family. In April 1819 he was promoted to the rank of lieutenant colonel and dined with President James Monroe and General Andrew Jackson.[44] In late 1820, Taylor took the 7th Infantry to Natchitoches, Louisiana, on the Red River.
