V.—The Blockade
The story of the development of the Grand Fleet would be incomplete without reference to the Blockade, and, in particular, to the work of the 10th Cruiser Squadron. In the early days of the War, the 10th Cruiser Squadron consisted of the ships of the “Edgar” class—vessels at least twenty years old; and during August, 1914, the Admiralty commissioned three armed merchant ships, the Mantua, Alsatian and Oceanic, to strengthen the squadron for blockade work; the latter ship was lost by shipwreck in September of that year.
The Blockade in those early days was carried out by the 10th Cruiser Squadron and by the other cruiser squadrons attached to the Grand Fleet. During November, 1914, the ships of the “Edgar” class were withdrawn owing to their unseaworthy condition, and the ships’ companies utilised to commission a number of additional armed merchant cruisers. By the end of December, 1914, the squadron consisted of eighteen ships, being raised later to a strength of twenty-four ships. A very large proportion of the officers and men of the reconstituted 10th Cruiser Squadron belonged to the Mercantile Marine.
The advent of so large a squadron of these vessels called for a considerable organisation for their maintenance; they were based on Liverpool for all the heavy work of upkeep, whilst a secondary advanced base at Swarbachs Minn, on the west coast of the Shetland Islands, was gradually developed, and obstructed against submarine attack. The work of organisation was carried out by Rear-Admiral de Chair, who commanded the squadron, ably seconded by Rear-Admiral H. H. Stileman, the Senior Naval Officer at Liverpool, to whom we were much indebted for hearty co-operation and efficient organisation at the base.
The work of the squadron consisted in intercepting and boarding all vessels bound into or out of the northern entrance to the North Sea, and this work could obviously not be carried out in the face of the German submarines without heavy risk to the ships. The danger was greatest during the operation of boarding, as the examining vessel was obliged to stop to lower the boarding-boat. As the number of German submarines increased, the squadron was necessarily withdrawn to positions further removed from the enemy submarine bases, and the Blockade line, after the spring of 1915, ran generally from the Orkneys and Shetlands past the Faroe Islands to Iceland, and when freedom from ice rendered passage round the north of Iceland possible, ships operated in that neighbourhood.
A careful organisation of the movements of the ships was necessary to cover such an immense area of the sea, and to provide that all ships should, as far as possible, be intercepted. Even in the case of ships of such large coal endurance as the armed merchant steamers, it was not possible to keep much more than one-half the number in commission on an average on the patrol line at the same time. The remainder were either in port refitting and refueling, or were en route to and from the bases. The distance from the middle of the patrol line to Liverpool was some 600 miles, so that two days were occupied in the passage each way.

Chart showing in pecked lines the area in which the ships of the 10th. Cruiser Squadron usually worked after about the middle of the year 1915; the positions of the ships being constantly changed.
Prior to this the areas were in the vicinity of A.B.C.D.G.
When going to or from Liverpool the ships had to run the gauntlet of enemy submarines, which were passing down the west coast of the Hebrides and Ireland, and as no destroyers were available with which to screen them against attack, the risk was considerable. They had also to face the constant danger of mine-fields. Several ships of the squadron fell victims to submarines or mines with a resultant heavy loss of life.
Whilst the ships were on patrol, the work of the boarding parties was very arduous. The preliminary examination could not be carried out without boarding, and the manner in which the boats of the squadron were handled in the very heavy weather, almost constant in northern latitudes, was a fine tribute to the seamanship of the officers and men. In this boarding work the fishermen of the Newfoundland Royal Naval Reserve, hardy and experienced seamen, rendered most conspicuous service.
The efficiency of the Blockade increased gradually from its inception, as is well known, and after a time the percentage of vessels that evaded the ships of the 10th Cruiser Squadron became so low as to be almost negligible. The procedure adopted was to send all ships, preliminary examination of which at sea aroused any suspicion, into Kirkwall or Lerwick harbours, where regular examination services were instituted. The ships were taken in under the supervision of an armed guard, sent on board from the boarding-vessel, and these guards underwent many unpleasant experiences. Several lost their lives in ships which were torpedoed by German submarines, and in many cases, particularly in badly found sailing ships, they underwent great hardships. The guards were also the means of saving more than one such ship from shipwreck, by working her themselves when the crew refused to do so any longer, and in all cases great tact and discretion on the part of the officer in charge, usually a junior officer of the Royal Naval Reserve, were necessary in his dealings with the neutral captains. The whole question of the efficiency of the Blockade—as shown by the returns furnished to me from Headquarters—was constantly under review by my Staff and myself.
The fate of the detained ship was decided in London on receipt of the report of examination. As was perhaps natural, the sentence on many ships’ cargoes pronounced in London was not accepted without question from the Fleet, and a good deal of correspondence passed with reference to individual ships. We, in the Fleet, were naturally very critical of any suspicion of laxity in passing, into neutral countries bordering on Germany, articles which we suspected might find their way into Germany, and constant criticisms were forwarded by me, first to the Admiralty, and, later, to the Ministry of Blockade, when that Ministry was established. The difficulties with which the Foreign Office was faced in regard to neutral susceptibilities were naturally not so apparent in the Fleet as to the authorities in London, and though many of our criticisms were perhaps somewhat unjustifiable, and some possibly incorrect, it is certain that in the main they were of use. Indeed, they were welcomed in London as giving the naval point of view. The decisive effect of the Blockade did not become apparent until the end, when the final crash came, and it was seen how supreme an influence on the result of the War this powerful weapon had exercised. Even those who during the War had been asking what the Navy was doing, recognised at the last how victory had been achieved, largely, as the result of the silent pressure of Sea Power.
