The Marines are deployed to back up the UN forces facing disaster in the Naktong Bulge and by the end of the week the tide has turned, and the crack North Korean 4th Division has been shattered. There is also fighting around the whole rest of the Pusan Perimeter, and it is shrinking from all the attacks, though on the east coast the battle goes in favor of the South Korean forces this week at Pohang-Dong.

The North Korean forces launch a huge new offensive against the entire Pusan Perimeter, hoping to break through at least somewhere along the line. They are aware that time is of the essence, for the UN forces grow in number daily, while they are losing a battle of attrition. Some new UN arrivals this week are the first British ground troops in Korea for the fight. Meanwhile, Douglas MacArthur's plans for his upcoming surprise counteroffensive hit all sorts of snags thanks to Korean geography.
