Were the Battle of Chosin Reservoir and Operation Grenade both wartime campaigns?
Operation Grenade During World War II, Operation Grenade was the crossing of the Roer (Rur) river between Roermond and Düren by the U.S. Ninth Army, commanded by Lieutenant General William Hood Simpson, in February 1945.
Kozara Offensive The Kozara Offensive, also known as Operation West-Bosnien by the Axis, was fought in 1942 on and around the mountain of Kozara in northwestern Bosnia. It was an important battle of the Yugoslav Partisan resistance movement in World War II. It later became an integral part of Yugoslav post-war mythology, which celebrated the courage and martyrdom of outnumbered and outgunned Partisans and civilians. Certain sources mistakenly identify the Kozara Offensive as part of Operation Trio.
