HX 47 was formed of two sections sailing from the Americas. The main body, of 37 ships departed Halifax on 2 June 1940[1] with ships gathered from the US eastern seaboard; it was led by convoy commodoreAdm. BS Thesiger RN in the steamship Pacific Pioneer. It was accompanied by its ocean escort, the armed merchant cruiserHMS Esperance Bay, and a local escort, a Royal Canadian Navy destroyer. Two ships dropped out early in the voyage; Randsfjord was damaged in collision with a Greek steamer and returned for repairs, and another returned to port for degaussing.
On 8 June the convoy was joined by BHX 47, 21 ships from the Caribbean and South America, that had gathered at Bermuda, departing there on 31 May escorted by the armed merchant cruiser HMSAscania and a local escort.[2]
On 14 June HX 47’s Western Approaches escort arrived. These were the sloops HMSSandwich, from escorting the outbound convoy OA 164, and HMSFowey from port following a refit. During the crossing three ships had dropped out of convoy; of these, Balmoralwood, was sighted on 14 June by U-47 and sunk, 70 miles from Cape Clear Island.[4]
That evening U-38 had attacked the Greek freighter Mount Myrto, on independent passage;[5] sighting HX 47 the U-boat left the freighter in a sinking condition and stalked the convoy. Attacking after midnight of 14/15 June U-38 sank two ships, the tanker Italia[6][7] and the freighter Erik Boye.[8] The U-boat escaped and HX 47 continued without further loss.
The main body of the convoy reached Liverpool on 17 June.[1]
Conclusion
Of the 58 ships that set out, two turned back and three were sunk. 53 ships made a safe and timely arrival. HX 47 was one of two trans-Atlantic convoys attacked during June, the other, HX 49, also losing three ships. During the month as a whole the UBW sank 63 ships in the Atlantic; most of these were unescorted vessels sailing independently.[9] June 1940 was the beginning of a marked increase in successes by the U-boat Arm, referred to by them as "The Happy Time".[10]
