As fourth personage, the writer designates himself, the promoter of the scheme, the indispensable link between the two nations. He undertakes to furnish reliable information as to the disposition of troops in England, as to the hydrography of the coast selected for the landing, as to the supplies available in its vicinity, and the strategic points to be seized. He proposes to be guide-in-chief to the expedition during transit. And in the meantime (when not otherwise employed) he was to reside at Norderney, in close touch with the other three, and controlling the commercial undertakings which were to throw dust in the eyes of the curious. [Memmert, by the way, is not mentioned in this memorandum.]
He speaks of the place “selected for the landing”, and proceeds to consider this question in detail. I cannot follow him in his review, deeply interesting though it is, and shall say at once that he reduces possible landing-places to two, the flats on the Essex coast between Foulness and Brightlingsea, and the Wash—with a decided preference for the latter. Assuming that the enemy, if they got wind of an invasion at all, would expect transports to be employed, he chooses the sort of spot which they would be least likely to defend, and which, nevertheless, was suitable to the character of the flotillas, and similar to the region they started from. There is such a spot on the Lincolnshire coast, on the north side of the Wash, _[See Map A]_ known as East Holland. It is low-lying land, dyked against the sea, and bordered like Frisia with sand-flats which dry off at low water. It is easy of access from the east, by way of Boston Deeps, a deep-water channel formed by a detached bank, called the Long Sand, lying parallel to the shore for ten miles. This bank makes a natural breakwater against the swell from the east (the only quarter to be feared); and the Deeps behind it, where there is an average depth of thirty-four feet at low-water, would form an excellent roadstead for the covering squadron, whose guns would command the shore within easy range. It is noted in passing that this is just the case where German first-class battleships would have an advantage over British ships of the same calibre. The latter are of just too heavy a draught to navigate such waters without peril, if, indeed, they could enter this roadstead at all, for there is a bar at the mouth of it with only thirty-one feet at high water, spring tides. The former, built as they were with a view to manœuvring in the North Sea, are just within the margin of safety. East Holland is within easy striking distance of the manufacturing districts, a vigorous raid on which is, the writer urges, the true policy of an invader. He reports positively that there exist (in a proper military sense) no preparations whatever to meet such an attack. East Holland is also the nearest point on the British shores to Germany, excepting the coast of Norfolk; much nearer, indeed, than the Essex flats alluded to, and reached by a simple deep-sea passage, without any dangerous region to navigate, like the mouth of the Channel and the estuary of the Thames from Harwich westwards. The distance is 240 sea-miles, west by south roughly, from Borkum Island, and 280 from Wangeroog. The time estimated for transit after the flotillas had been assembled outside the islands is from thirty to thirty-four hours.
