Maps: the course of the war

Stage one:
25 June - 1 August 1950
The initial period of the war was a desperate struggle between the two
forces, in which UN forces were close to being driven out of Korea. This
period ended with the establishment of the Pusan perimeter, a defensive
line 230 km long, which protected the main approaches to the strategically
vital southern port of Pusan.


Stage Three: 25 November 1950 - 22 April 1951
In this phase, over half a million Chinese troops entered the war, launching
several offensives that pushed the UN forces almost back to the 38th parallel.
In the bitter fighting of the winter of 1950-51, heavy losses were sustained
by both sides. After being pushed back from the Yalu River and the Chinese
border, the UN Command was forced to abandon first Pyongyang on December
5, and then Seoul on January 4. General Douglas MacArthur, Commander of
the UN forces in Korea, was dismissed by US President Harry S. Truman
on 11 April. There had been public dispute between the two men, as Truman
had countermanded MacArthur's desire to extend the war into China. MacArthur
was replaced by General Walton Walker. When Walker was killed in a road
accident, General Matthew Ridgeway took his place.

Stage Four: 22 April 1951 -
27 July 1953
As armistice negotiations began, a stalemate developed on the battlefield,
with action consisting mostly of trench warfare. The battle line surged
southwards again as the Chinese launched a major offensive on 22 April
1951. It met with stubborn resistance in several sectors, particularly
those held by the Gloucestershire Regiment on the Imjin River, north of
Seoul. The Canadian and Australian battalions at Kapyong, further west,
also checked the advance. By 30 April 1951, the Chinese thrust towards
Seoul had been turned back and the battle line again moved northwards.
In July 1951, HMAS Murchison engaged North Korean forces on land
as part of Operation Han. As the stalemate continued, each side vyed for
control of key local features. One of these was Maryang San, captured
by 3 RAR in early October. General Mark Clark replaced General Matthew
Ridgeway as Commander of the UN forces on 12 May 1952. In December 1952,
1 RAR led Operation Fauna. The battle at The Hook (Samichon) in July
1953 was Australian troops' last action of the war.
