Pre-Dreadnought ~ Further operations

I'm shaping up the next scenario in the 1905 Moroccan Crisis series of linked games. This will involve three armoured cruisers, the two Prinz Adelbert class ACs SMS Prinz Adelbert and Friedrich Karl, and SMS Prinz Heinrich along with an escort of light cruisers and destroyers. The objective is to break out into the North Atlantic and commence commerce raiding on British and French shipping. 

Under this scenario the armoured cruiser force leaves Heligoland at dusk on the day of the Battle of the Humber. Security is absolute. Unlike the previous clash where British Admiralty intelligence intercepted German naval wireless traffic and was able to forewarn the fleet of the German move, the cruiser force received all orders via telegraph and fleet courier. 

At the same time a Royal Navy division from the Channel Squadron is on the move, destination Heligoland. Composed of four Royal Sovereign class battleships and escorts, its objective is to bombard and neutralise shore defences and destroy any enemy warships in the area. 

Green arrow: German plotted course. Red: British course.

To set things in context: The Royal Navy was already on a high state of alert following the October 21st 1904 Dogger Bank Incident where a Russian fleet transiting the North Sea opened fire on British fishing trawlers in the mistaken belief they were Japanese torpedo boats. Yes, quite. Although the Russian's profuse apology and compensation mollified British public opinion, the Russo-Japanese War is still in progress and the Royal Navy remains watchful against further 'incidents.'

I'm thinking of taking a leaf out of the Traveller SF rpg book by drawing up a chart of shipping encounters which both sides may come across en-route. There'll be a chance of a wireless equipped vessel - neutral or hostile - transmitting the coordinates of the encountering squadron to all and sundry. This may or may not give advanced warning of an approaching force.
