===The Oregon Maneuver===
In the wake of Guadalcanal's conquest, the state of Patch's health, battered by his bout of pneumonia, tropical dysentery and malaria, forced George Marshall to recall him back to the U.S., after recovering from his illness, he took command in May 1943 of the [[IV Corps (United States)|IV Corps]] at [[Fort Lewis (Washington)|Fort Lewis]], [[Washington (state)|Washington]].{{sfn|English|2009|p=168}} That fall he commanded the 100,000 man strong [[Oregon Maneuver]] in central Oregon, the largest training exercise of World War II, designed to test American units prior to deployment in support of Allied combat operations in both the European and Pacific Theaters. In early [[1944]] he took the corps, then just a headquarters, overseas to [[Algiers]], [[Algeria]] to the [[Mediterranean Theater of Operations, United States Army|Mediterranean Theater of Operations]] (MTO). By mid-summer he would put his Oregon Maneuver experience to the test in [[Operation Dragoon]], the amphibious assault of southern France that was pressed clear to the [[Alsace-Lorraine]] on Germany's southwest flank before year's end.{{sfn|English|2009|p=166}}
