On 22 April, Bayern and the rest of the German fleet assembled in the Schillig Roads outside Wilhelmshaven and departed the following morning at 06:00. Heavy fog forced the Germans to remain inside their defensive minefields for half an hour. Hipper's forces were west of Egerö, Norway, by 05:20 on 24 April. Despite the success in reaching the convoy route undetected, the operation failed due to faulty intelligence. Reports from U-boats indicated to Scheer that the convoys sailed at the start and middle of each week, but a west-bound convoy had left Bergen on Tuesday the 22nd and an east-bound group left Methil, Scotland, on the 24th, a Thursday. As a result, there was no convoy for Hipper to attack.
