Last Tuesday [June 12], proceeded to sea in company with [HMS] Implacable, Ruler, the 4th Cruiser Squadron [HMS Swiftsure, HMS Argonaut, HMS Black Prince, HMS Euryalus, HMNZS Gambia], and 24th Destroyer Flotilla, comprizing [HMS] Tenacious, Termagant, Troubridge, Teazer and Terpischore, our objective being the Jap[anese] held island of Truk, once an enemy base in the SW Pacific. It was by-passed in the advance to the Philippine Islands but has been under almost daily aerial bombardment by the US Air forces ever since.
The operation and our force were designated respectively Inmate and TG 111, Rear Admiral Brind flying his flag in [HMS] Swiftsure. Air exercises were carried out during the two days (T-2 & T-1) spent in reaching the strike area. We arrived there, about 70 miles to the SW of Truk, early on Thurday morning [June 14]. At first light, Implacable flew off a strike of about 20 aircraft – Seafires, Avengers, & Fireflies. Soon after this was completed, we were turned out to a Repel Aircraft Alarm. The Bogey was however identified as an Air/Sea Rescue Catalina patrolling the area. Two hours later, another strike was flown off, and the first landed on. This routine was continued throughout the hours of daylight, a total of 6 waves being sent off. Casualties were one Seafire, lost on operations, and 2 Avengers which fell into the sea on taking off. The crews of the latter were rescued by Destroyers. Two Fireflies and one Avenger were slightly damaged by enemy “flak”. No air opposition was met by our attacking planes, and Airfields, aircraft, Radar installations & gun positions were bombed & straffed with fair success.
At frequent intervals throughout the day, the A/S R [Air/Sea Rescue] craft was cause for for alarm reports, & our fighters were constantly investigating. The crew of the Catalina must have been impressed, & probably a little worried, by the attention paid them.
During daylight hours, a two watch system was in force, but after dark, this was broken down into 1 in 4. Night intruder patrols were sent off by [HMS]Implacc, the last landing on again soon after midnight. One Avenger drove into the sea over the carrier bows. Searchlights were quickly organized, and survivors were rescued by a Destroyer. When we left harbour HMS Ruler carried on board one only Walrus for rescue work. Unfortunately, this aircraft was blown overboard in a strong wind at night, which left the carrier without any useful purpose in life.
