Early this morning soon after dawn, we were the target of a throw off shoot by [HMS] Implac’s. 4.5″s. We were stationed to the north of the carrier on her port beam & 4 mins of 12 salvoes were carried out. On completion, we retaliated by firing off 16 six inch two gun broadsides 6° astern of [HMS] Implac, the first half from A turret & the 2nd half by Y turret. During the forenoon, planes from the carrier did some dummy runs on us to give the close range weapon crews some aiming practice. Tonight carried out Encounter exercise with carrier & destroyers [HMS Tumult & Terpischore]. Our star shell on this occasion was better than usual, our accuracy actually causing some concern that we might hit something. At Midday our position was 9° 35.5′ N, 65° 34′ E.
