An other when if in history:
If the german-prussian troops in 1870/71 war against france didn't involve in the Paris Commune affair - there might have been an Commune goverment. In 1872 the Times corrospondent in Paris asked the minister of naval affairs: "What will the new french goverment do to face the new mastless british battleship HMS Devastation?"
And the Minister of naval affairs answered proudly: "Rien de tout! What meens absoloutly nothing!"
And so the french build a overwelming coastal battleship with an 42cm breech loader in single barreled turrets with an enormous armour of nearly 1m. Four turrets in en echelon so 3 barrels are able to fire ad any enemy before the ram. .
And the Minister didn't lie - she was called:

The WLmodel. As easily to see the fockmast was altered to a non crowsnest/lookout mast because the ship will fire on mid distance - so it is not of importance.
