Hipper's force included the battlecruisers Moltke, Von der Tann, and Seydlitz, his flagship, and the large armored cruiser Blücher, along with four light cruisers. The flotilla arrived off Great Yarmouth at daybreak the following morning and bombarded the port, while the light cruiser Stralsund laid a minefield. The British submarine HMS D5 responded to the bombardment, but struck one of the mines laid by Stralsund and sank.
