As the tittle says, I read of the blockade etc.. But why didnt the superiorly numerous allies try to bypass Belgium and break into Baltic and try to land troops there. What stopped them and was such an action ever considered?
Ah thank you. So problem was neutral Denmark.
How hard or easy would it be to go slowly and remove German mines with minesweepers covered by Royal navy and French navy..
Several things I imagine:
- As others have already mentioned both Denmark and Sweden had declared neutrality. And said that they would defend the entrance to the Baltic Sea against all attackers.
It wouldn´t look good if Britain which entered the war because of poor little Belgium would now attack a neutral country too? - Look at a map.
You essentially have three narrow "ways" from the Kattegat into the Baltic Sea. Easy to mine, easy to defend with coastal artillery. Add in small torpedo boats and submarines and breaking through would look very costly indeed.
(The Little Belt is 50 km long, the Great Belt 60 km and the Oresund looks like 40-50 km too.)
(A coastal gun barrel can be raised to a higher elevation than a gun in a ship turret, meaning more range and plunging fire.) - What percentage of the Royal Navy do you want to send there?
If you only send a small part then the German High Sea Fleet might surprise and defeat them. If you send a large part then you have more targets for submarines and less ships are available elsewhere. - Damaged ships will have to return to Britain for repairs.
If I were a German admiral I´d place submarines and Zeppelins close to the Skagerrak to take a shot at damaged ships. - Without a harbor all ships have to return to Britain for refueling and resupply. Which means that lots of ships will be in action almost all of the time. Less rest for crews and less time for maintenance.
- And even if despite all this you break through you still have to face the German fleet with their bases close by while the next Entente bases are either back in Britain or Russian St. Petersburg. Plus you´ll first need an army to occupy Denmark to secure the water lanes so that you can resupply your landed troops in Germany.
Meaning that you need two armies if you even want to think abut landing one in Germany. Those soldiers have to come from somewhere?
If the British lose several dreadnoughts the German fleet might become more adventurous too.
And if Baltic was off the limits, why not try to go for North coast of Germany on the other side, where Hamburg and Wilhelmshaven are at?
Once again look at a map.
First of all at the start of the war Germany declared the whole German Bight a war zone with mine fields. Roughly in a quarter circle from Borkum / Emden at the Dutch-German border to above the island of Sylt at the Danish-German border.
Inside that zone you have the island of Heligoland, a´naval fortress with 12 inch guns in armored cupolas.
Plus most of the islands close to the coast had been fortified too. IIRC Wangerooge, Langeoog, Norderney and Borkum all had coastal batteries with 11 or 12 inch guns.
And the final defenses (additional coastal artillery) were at the river entrances and the entrance to the Jadebusen (Wilhelmshaven).
Also, zoom in and look at the light green color between the islands and the coast. That´s the tidal flats. Above water at low tide (except for some channels) and below water at high tide.
Pretty difficult to plan an amphibious operation here especially if you have to deal also with German small craft hiding in the channels only known to them.
You could invade an island sure (with only a small fishing harbor.
But then how to get your soldiers and equipment from that island to the mainland? Incredibly risky and time consuming. Almost certain to fail.
And Hamburg and Wilhelmshaven?
Well look at Hamburg. It´s quite a long way upriver the river Elbe to reach Hamburg. With quite a few coastal artillery batteries stationed along the way. Starting around Cuxhaven.
And Wilhelmshaven?
There´s only a narrow darker green channel (deeper water level) starting at the island of Wangerooge and then going on for 50 or 60 km till you reach Wilhelmshaven. And also coastal artillery on both sides.
It´s the same for Bremerhaven and Bremen.
You try that and the Royal Navy will lose a lot of ships.
And probably not much to show for it.
There is a reason why the Entente in WW1 didn´t try both options.
The same reason why the Allies in WW2 didn´t try an invasion of the German North Sea coast.
