Both sides claimed victory. The British lost more ships and twice as many sailors but succeeded in containing the German fleet. The British press criticised the Grand Fleet's failure to force a decisive outcome, while Scheer's plan of destroying a substantial portion of the British fleet also failed. The British strategy of denying Germany access to both the United Kingdom and the Atlantic did succeed, which was the British long-term goal. The Germans' "fleet in being" continued to pose a threat, requiring the British to keep their battleships concentrated in the North Sea, but the battle reinforced the German policy of avoiding all fleet-to-fleet contact. At the end of 1916, after further unsuccessful attempts to reduce the Royal Navy's numerical advantage, the German Navy accepted that its surface ships had been successfully contained, subsequently turning its efforts and resources to unrestricted submarine warfare and the destruction of Allied and neutral shipping, which—along with the Zimmermann Telegram—by April 1917 triggered the United States of America's declaration of war on Germany.
