'Coullie' was a British programme carrierborne air attacks on the Japanese-occupied Nicobar islands group and provision of air cover for the British minesweeping forces near Phuket island off the western coast of Thailand (5/10 July 1945).

In July Admiral Sir Arthur Power’s East Indies Fleet began the task of sweeping mines from the approaches to possible Allied landing places on the western side of Thailand and Malaya for operations such as 'Roger' and 'Zipper'. In the period between 5 and 10 July some 167 moored mines were destroyed off the eastern coast of the most northerly island of the Nicobar islands group in an operation commanded by Vice Admiral H. T. C. Walker and covered by the escort carriers Ameer and Emperor, the light cruiser Nigeria, and the destroyers Roebuck, Eskimo and Vigilant. This naval force also bombarded Japanese positions on the islands as well as Nancowry to the south, and made a number of air attacks. In the period 24/26 July the area off Phuket island was swept for the loss of the minesweeper Squirrel in an operation covered by the battleship Nelson, the heavy cruiser Sussex, two escort carriers and four destroyers. This force also carried out a number of air attacks on targets on the Kra isthmus.

On 26 July the first kamikaze attacks in South-East Asia took place in the form of attacks on this naval force. Three of the attacking aircraft were shot down by Sussex and Ameer, but one succeeded in hitting the minesweeper Vestal, which caught fire and was later sunk. This small action proved to be the last of the war in which ships of the East Indies Fleet were involved.
