The Nyon Agreement

[Dreamslayer]

Arrangement de Nyon / The Nyon Arrangement

On September 10-14, 1937, a diplomatic conference was held in Nyon, Switzerland.

During the Spanish Civil War, nine Powers agreed to take collective measures to suppress attacks by submarines against merchant vessels. The Agreement refers in the preamble to the provisions of the London Treaty of 1930 and the procès-verbal of 1936 concerning submarine warfare. In the Supplementary Agreement of 17 September 1937 the same Powers made the principles of the first Agreement applicable to attacks by surface vessels and aircraft.

In the game you can see almostly unrestricted naval warfare but it was a little more complicated in the actual history.

In-game of course, the Nationalist player can use German/Italian ships without restrictions (other than withdrawl dates)

It's very difficult to model some sort of restraint, but I do think that benefits the Nationalist player more than it should, especially for the surface ships. I don't think Admiral Scheer , for example, would be aggressively hunting shipping like you can do in-game, IIRC her orders were to cover convoys and defend if attacked. Germans protested when Deutschland was hit by a bomb, retaliated by a shore bombardment IIRC, and left it at that.

In-game, those cruisers can temporarily tip the naval balance and cause lots of damage to the Republican Navy, which gets no reinforcements, temporary or otherwise

(Subs I think are different; they were used more aggressively, because of a certain deniability there)

What is the solution then? To use the Home Rules?

What is the solution then? To use the Home Rules?

Not sure....it's a tough one to House Rule, because the ship's captain is going to do what he's going to do

All I can think of is:
1. House Rule that you can't order a ship to a hex more than 10 hexes from Palma, or in the Mediterranean more than 5 hexes from Ceuta (that keeps them more or less to Balearic Islands, Atlantic, and the Strait, where they were used historically). Ship may sail on it's own past those limits, can't help that
2. House Rule that German/Italian ships cannot be used on Bombardment missions unless that ship is attacked first
3. OR, restricting those ships to TRANSPORT missions (where they will serve as convoy escorts)

I don't think Subs should be restricted; the Italians and Germans claimed all the time "It wasn't my sub". You can't do that with a surface ship.....

Convoys from Napoli to Palma need escorts firing AA guns. That is a good job for the Italians.

Some Italian submarines are SSMs and can lay those mines.
