what if German prioritize u-boats late 1914. let say German lose on raid of Scarborough Dec 1914 hipper 4 battle cruisers in British ambush. German loss ITTL will convince HSF that large surface battle is hopeless same result as battle of Jutland IOTL. German navy after Jutland became convinced that large surface battle is suicide for HSF. that made unrestricted sub-warfare only solution.German navy never build u-boats at max capacity in IOTL for fear that Germany will have large surplus of u-boats postwar. as long Erich Von Falkenhayn is army chief unrestricted sub-warfare will never happen.
but if German navy became convinced that sub-warfare is only game in town in late 1914.
let say that Germany have 20% more u-boats in end of 1916. in IOTL 1916 German u-boats where send to ambush grand fleet but if German send u-boats to sink entente shipping .u-boats can sink million more shipping. extra 20% u-boats that Germany build to end of 1916 can sink half million ton shipping.
so German sink extra 1.5 million entente by end of 1916.
in IOTL German sink 6.5 million ton shipping in 1917 and 2.5 million ton in 1918. so German sink 1.3 million ton in 1917 and .5 million ton sunk in 1918. total 1.3+0.5=1.8 million ton extra sunk of entente shipping in 1917 and 1918
what are effect if entente lose 1.5 million ton of shipping in end 1916 and 1.3 million ton in 1917 and 0.5ton in 1918
