Indeed. Mahan was very influential, and the reason everybody wanted a battle line. He perhaps neglected other forms of naval warfare, namely Guerre de Course. Had the Imperial German Navy invested in more light cruisers and U-boats they’d have had the material to throttle Britain. Instead they built a battle line that was effectively blockaded for much of the war. They had a puncher’s chance however, and their ships were tough and gunnery excellent.
But the Kaiser was afraid to lose his precious navy and especially after Jutland. (my dad being Navy had me read a lot of naval history).
