"Lübeck" and several other cruisers and torpedo boats bombarded the city on 6 May and patrolled to ensure no Russian naval forces attempted to intervene. "Konteradmiral" (Rear Admiral) Albert Hopman, the commander of the reconnaissance forces in the Baltic, conducted a major assault on Libau the next day in conjunction with an attempt by the German Army to seize the city. "Lübeck" joined the armored cruisers , , and , the elderly coast defense ship , and the light cruisers "Augsburg" and "Thetis". They were escorted by a number of destroyers, torpedo boats, and minesweepers. The IV Scouting Group of the High Seas Fleet was detached from the North Sea to provide cover for the operation. The bombardment went as planned, though the destroyer struck a mine in Libau's harbor, which blew off her bow and destroyed the ship. German ground forces were successful in their assault however, and took the city. A week later, on 14 May, "Lübeck" was to lay a minefield off the Gulf of Finland with "Augsburg", but Russian submarines in the area convinced the Germans to cancel the operation. While patrolling off Libau on 28 June, "Lübeck" clashed with a group of Russian destroyers in an inconclusive action. On 1 July, the minelayer , escorted by the cruisers "Lübeck", "Roon", and "Augsburg" and seven destroyers, laid a minefield north of Bogskär. While returning to port, the flotilla separated into two sections; "Augsburg", "Albatross", and three destroyers made for Rixhöft while the remainder of the unit went to Libau. "Augsburg" and "Albatross" were intercepted by a powerful Russian squadron commanded by Rear Admiral Mikhail Bakhirev, consisting of three armored and two light cruisers, resulting in the Battle of Åland Islands. Karpf, the flotilla commander, ordered the slower "Albatross" to steam for neutral Swedish waters and recalled "Roon" and "Lübeck". "Albatross" was grounded off Gotland and "Augsburg" escaped, and the Russian squadron briefly engaged "Lübeck" and "Roon" before both sides broke contact. In the course of the action, "Lübeck" scored eight hits on the powerful armored cruiser , and she was not hit by Russian fire in return.
