Starting in November, I Squadron—less the "Wittelsbach"-class ships, which were still occupied with trials—conducted a number of short cruises, culminating in the annual winter cruise that began on 1 December. The ships steamed into the Kattegat and stopped in Frederikshavn, Denmark, before continuing on to Bergen, where they stayed from 6 to 10 December. "Kaiser Friedrich III" and the rest of the squadron returned to Kiel, arriving two days later. On 2 April 1903, the squadron went to sea again, and began gunnery training two days later. These exercises continued for the rest of the month, interrupted only by heavy storms. A major training cruise followed the next month; on 10 May the ships departed the Elbe river and made their way into the Atlantic. They cruised south to Spain, passing Ushant on 14 May and reaching the Iberian Peninsula five days later. There, they conducted a reconnaissance exercise off Pontevedra before anchoring in Vigo on 20 May. Prince Heinrich left "Kaiser Friedrich III" for a visit to Madrid. After he returned, the squadron departed Spain on 30 May. The ships passed through the Strait of Dover on 3 June and continued into the Kattegat. There, they rendezvoused with the torpedo boats of I "Torpedobootsflotille" (Torpedo Boat Flotilla)—commanded by "Korvettenkapitän" (Lieutenant Commander) Franz von Hipper—for a mock attack on the fortifications at Kiel.
