It sinteresting how different people see Jutland.
wethe rit was a tactical/strategic/deciding/minor victory of Germany/the UK...
Its all true - partly...
I tend to think it was a draw.
Neuither the HSF nor the RN achieved the goal they started with.
Both went away roughly the same power ratio they had before (UK had more in the beginning and lost more too)
Both learned from the experience (regarding BCs and shells, gunfire)
But it was a boost to the Kaisers (and Germanys) confidence...
Jutland was never a battle the UK couldend the war with (Germany was too strong on land), but as someone remarked

it could have cost the UK the war... - if the HSF had prevailed.
One might say that the RN did not manage to destroy the HSF, insofar the Brits failed, but the HSFstayed in harbor from then on - insofar the RN suceeded.
THE HSF did retreat (insofar they "lost") but they did dish out a lot of pain to the RN insofar they "won"...
IMHO Jutland did show one thing early - battlewagons were on the decline - an afternoon and you lose 1.000s of men and millions of Pounds - often to only a few shots. But even if you "suceed" the war is not won..
