During the early part of 1917 the enemy carried out a few destroyer raids both on English coast towns in the vicinity of Dover and the French ports of Dunkirk and Calais. As a result of these raids, which, though regrettable, were of no military importance, a good deal of ill-informed criticism was levelled at the Admiralty and the Vice-Admiral commanding at Dover. To anyone conversant with the conditions, the wonder was not that the raids took place, but that the enemy showed so little enterprise in carrying out—with the great advantages he possessed—operations of real, if not vital, military value.
The only explanation is that he foresaw the moral effect that his tip-and-run raids would produce; and he considered that the effect of the resulting agitation might be of no inconsiderable value to himself; the actual damage done was almost negligible, apart from the loss of some eight lives, which we all deplored. It is perhaps natural that people who have never experienced war at close quarters should be impatient if its consequences are brought home to them. A visit to Dunkirk would have shown what war really meant, and the bearing of the inhabitants of that town would have taught a valuable lesson.
The conditions in the Straits have already been mentioned, but too much emphasis cannot be laid on them. The enemy who possessed the incalculable advantage of the initiative, had at his disposal, whenever he took heart to plan an attack, a force of at least twenty-two very good destroyers, all unfortunately of higher speed than anything we could bring against them, and more heavily armed than many of our destroyers. This force was based within seventy miles of Dover, and as the Germans had no traffic of any sort to defend, was always available for offensive operations against our up and down or cross-Channel traffic. Our Dover force was inferior even at full strength, but owing to the inevitable absence of vessels under repair or refitting and the manifold duties imposed upon it, was bound to be in a position of marked inferiority in any night attack undertaken by the Germans against any objective in the Straits.
The enemy had a great choice of objectives. These were: first, the traffic in the Channel or the destroyers watching the Straits (the most important military objective); second, the merchant ships anchored in the Downs; third, the British monitors anchored off Dunkirk; fourth, the French ports, Dunkirk, Boulogne and Calais, and the British port of Dover; and fifth, the British undefended towns of Ramsgate, Margate, Lowestoft, etc., which German mentality did not hesitate to attack.
