The Division's total front line extended about 18000 yards, with different Regiments defending the same areas at different times, along with other UN forces. The US 2nd Infantry Divisions and 1st Marine Divisions were probably the most prominent, and took part in savage fighting throughout the area. One of the most bitterly contested battlegrounds was called 'The Hook'.

The Hook was part of an east-west ridge four miles northwest of the confluence of the Samichon and Imjin Rivers. Some of the most savage hand-to-hand fighting there was by the Black Watch 1st Battalion in November of 1952, and the French Battalion and 2nd ID units in March of 1953. The Marines fought several bitter actions around the Hook as well, and about a mile southwest in attacks on Chinese-held Hill Detroit. RAR did its share.

The distance from the enemy along our general divisional front differed widely in many places. The Hook saw our troops actually sharing the same feature as the Chinese, only some 300 yards apart. So close to the enemy, day-to-day living conditions were very tenuous.
