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.
Battle of Kapyong The Battle of Kapyong (Korean: 가평전투 , 22–25 April 1951), also known as the Battle of Jiaping (), was fought during the Korean War between United Nations (UN) forces—primarily Australian, Canadian and New Zealand—and the Chinese communist People's Volunteer Army. The fighting occurred during the Chinese Spring Offensive and saw the 27th British Commonwealth Brigade establish blocking positions in the Kapyong Valley, on a key route south to the capital, Seoul. The two forward battalions—3rd Battalion, Royal Australian Regiment (3 RAR) and 2nd Battalion, Princess Patricia's Canadian Light Infantry (2 PPCLI)—supported by a New Zealand artillery battery, occupied positions astride the valley and hastily developed defences. As thousands of South Korean soldiers began to withdraw through the valley, the Chinese infiltrated the brigade position under the cover of darkness, and assaulted the Australians on Hill 504 during the evening and into the following day.
