On 19 August, two British tankers became stragglers and one of these, the La Brea, was sighted by U-48 on the morning of 24 August. The U-boat sank the ship during the afternoon and then continued northwest, while that evening the main convoy split with 20 ships proceeding to Methil in section HX-65A and 25 ships proceeding to Liverpool in section HX-65B.
