There are two outlets to the North Sea, one wide to the north and west beyond the Shetlands, the other narrow and shallow to the south-west through the Straits of Dover. The Straits are only twenty-one miles wide; opposite the north of Scotland the Sea is 300 miles wide. But before German battleships or cruisers could get away towards the wide north-western outlet beyond the Shetlands they would have to steam some 400 miles north of Heligoland. Except for the Pacific Squadron based upon Tsing-tau in the Far East and cruising upon the east and west coasts of Mexico, all the fleets of our enemy were at his North Sea ports or in the Baltic—a land-locked sheet of water which for the moment is out of our picture. From Heligoland to Scapa Flow in the Orkneys—where Admiral Jellicoe had his headquarters and where he had under his hand twenty-two of our most powerful battleships—is less than 550 miles. Jellicoe had also with him large numbers of armoured and light cruisers. In the Firth of Forth, less than 500 miles from Heligoland, Admiral Beatty had five of the fastest and most powerful battle cruisers afloat and great quantities of lighter cruisers and destroyers. In the Thames, about 350 miles from Heligoland, lay most of our slower and less powerful pre-Dreadnought battleships and cruisers, vessels of a past generation in naval construction, but in their huge numbers and collective armaments a very formidable force to encounter in the narrow waters of the Straits of Dover. Three possible courses of action lay before the German Naval Staff. They had at their disposal seventeen battleships and battle cruisers built since the first _Dreadnought_ revolutionised the battle line, but, as I have already pointed out, these vessels, class for class and gun for gun, were lighter, slower, and less well armed than were the twenty-seven great war vessels at the disposal of Jellicoe and Beatty. The Germans could have tried to break away to the north with their whole battle fleet, escorting all their lighter cruisers, in the hope that while the battle fleets were engaged the cruisers might escape round the north of Scotland, and get upon our trade routes in the Atlantic. That was their first possible line of action—a desperate one, since Jellicoe and Beatty with much stronger forces lay upon the flank of their course to the north, and the preponderating strength and swiftness of our light and heavy cruisers would have meant, in all human probability, not only the utter destruction of the enemy’s battle fleet but also the wiping out of his would-be raiders. Our cruisers could have closed the passages between the Orkneys and Iceland long before the Germans could have reached them. This first heroic dash for the free spaces of the outer seas would have been so eminently gratifying to us that it is scarcely surprising that the Germans denied us its blissful realisation.
