The term "Battles of the Outposts" encompasses the fighting that took place in the final two years of the Korean War. In the first year of the war sweeping movement up and down the peninsula characterized the fighting. Combat raged from the 38th Parallel south to the Pusan Perimeter then, with the landing at Inchon and the Perimeter breakout, up to the Yalu, and finally a retreat south again in the face of the massive Chinese intervention.
