The Alice Moller had to return to Colombo with defects.
The convoy sailed from Colombo on 3 February 1942 and was escorted initially by the British heavy cruiser HMS Cornwall (Capt. P.C.W. Manwaring, RN) and the Australian minesweepers HMAS Bathurst (Lt.Cdr. A.V. Bunyan, RANR(S)) and HMAS Lismore (Lt.Cdr. S.H. Crawford, RANR(S)).

On 11 Februry 1942, the British heavy cruiser HMS Exeter (Capt. O.L. Gordon, MVO, RN) apparently joined the escort and remained with it until 13 February.
On 13 February 1942 the convoy was split up and the Filleigh Lulworth Hill, Yoma, Hai Lee and Hermion arrived at Oosthaven, Sumatra. They were escorted by HMAS Hobart and HMIS Jumna. HMIS Jumna remained at Oosthaven to provide A/S protection for that port together with the Australian minesweepers HMAS Goulburn (Lt. B. Paul, RANR(S)) and HMAS Burnie (T/A/Lt.Cdr. G.E.
