The United States Marine Corps in October, and later the Scottish Black Watch regiment in November, had successfully held the Hook during the second battle, against PVA assaults.

This ridge was a place of tactical importance in the 1st Commonwealth Division sector: it was a potential attack route which the PVA needed to take before assaulting Yong Dong, and opening up an invasion route to Seoul, the South Korean capital.

This was then followed up in a major action over the 28–29 May following heavy initial artillery and mortar fire, after which the PVA infantry attacked in force.

[3] Casualties from other supporting units: For their action, the Duke of Wellington's Regiment was awarded the Battle Honour The Hook 1953.

[7] Shortly after on 2 June 1953, to mark the Coronation of Queen Elizabeth II the division's artillery fired red, white and blue smoke shells onto the PVA lines (a "feu de joie"), followed by a salute from Centurion tanks which fired HE shells onto a single target.

[8] The Hook was defended on a fourth occasion immediately prior to the armistice by an Australian infantry battalion, a New Zealand artillery regiment and two US infantry regiments, supported by British tanks, during the Battle of the Samichon River.
