In early September, "Prinz Eugen" supported a failed attempt to seize the fortress island of Hogland. The ship then returned to Gotenhafen, before escorting a convoy of ships evacuating German soldiers from Finland. The convoy, consisting of six freighters, sailed on 15 September from the Gulf of Bothnia, with the entire Second Task Force escorting it. Swedish aircraft and destroyers shadowed the convoy, but did not intervene. The following month, "Prinz Eugen" returned to gunfire support duties. On 11 and 12 October, she fired in support of German troops in Memel. Over the first two days, the ship fired some 700 rounds of ammunition from her main battery. She returned on the 14th and 15th, after having restocked her main battery ammunition, to fire another 370 rounds.
