'HF' (ii) was the designation of Allied convoys (together with a numerical and sometimes a literal suffix) plying the route from Halifax, Nova Scotia, to St John, New Brunswick, and as such reciprocals of the 'FH' series (September 1942/May 1945).
The first of these 173 convoys was HF.1 of 13/15 September 1942 with the 3,708-ton British Cathcart, 2,904-ton Yugoslav Neti and 2,060-ton British Sarnolite but no escorts, and the last was HF.177 of 20/22 May 1945 with the 5,200-ton British Charlton Hall, 5,275-ton Greek Dimitrios Inglessis, 3,231-ton Norwegian Iron Baron and 10,307-ton British Menelaus but no escorts.
