"Upholder" and "Unbeaten" were ordered by Simpson to sail again on 24 June. A convoy of four liners was sailing from Naples to Tripoli. Wanklyn took a position eight miles to the west in error. Hydrophones picked up the convoys propeller noises and occasional depth charges but saw nothing. The boat was recalled and arrived in Malta on 27 June, making this her shortest patrol. It was the first patrol in many that Wanklyn could not fly the Jolly Roger to denote a kill. During these patrols, "Upholder" hosted war correspondent and future actor Commander Anthony Kimmins. Kimmins contributed an article to "The Listener" magazine, which was broadcast on the BBC Home Service on 20 February 1942.
