On Friday morning [15 June], CS4 [Cruiser Squadron 4] transferred his flag from HMS Implacable to HMCS Uganda. The 4 cruisers and 3 destroyers then proceeded to the Eastern side of Truk and, lying just outside the reef in three groups, commenced to bombard air installations and gun positions. HMS Swiftsure & Teazer opened fire first and the remainder followed in quick succession. The particular targets were airstrips on Eten Island and gun positions on Uman. After putting our fire on to the the airfield the spotting aircraft developed engine trouble so we just had to blaze away without further corrections. The enemy did not return fire. After firing about 200 rounds altogether, we received the order to break off the action, and all the bombading force withdrew to the eastward, meeting up with [HMS] Implacable about noon.
Results of our shoot at the airstrip were described as good, as were the Destroyers’ efforts against the smaller gun positions. The other Cruisers did not apparently achieve all that they might have done, as the spotting aircraft were hindered by flak & for other reasons. Altogether, it seems to me that the operations against Truk have been more use as a practice for our forces than for any material damage that might have been inflicted on the enemy.
During the afternoon, the flag was transferred back to [HMS] Implacable, and further strikes flown off. Intruder patrols were sent out during the evening also. Shortly before midnight, course was set for Manus.
Yesterday morning, Saturday, we joined up with [HMS] Ruler & escort. A certain amount of interest was aroused later on by a depth charge attack by Destroyers on an asdic contact.
Today we entered Seeadler Harbour at 10 mins to 9, and secured in our old berth. Commenced fuelling soon after from [RFA] Rapidol.
