The enterprise divides itself naturally into three main phases, namely, the Approach, the Attack, and the Retirement; as far as practicable Part II will describe each of these phases in turn, whilst dealing more or less separately with the work of each class of vessel. {165} CHAPTER I THE START. THE OVERSEA PASSAGE The break of dawn on April 22, 1918, the first of the seven days of our tabulated period, found many anxious individuals on deck discussing the chances. There was an almost entire absence of wind; the sea was consequently as smooth as the proverbial mill-pond. The general feeling amongst us was that of straining-at-the-leash. We had suffered two major disappointments during the previous period, but we instinctively felt that we had now arrived at a period of maximum anxiety--we knew that the coming week would settle the matter once and for all. Presently light airs from the northward began to catspaw the glassy surface and to increase in frequency and strength until they settled down to a real northerly breeze. Our hopes ran high, but the matter of visibility still claimed our attention. There was the usual early morning mist; this was quickly dispelled when the sun rose above the horizon. It soon became evident that our hopes for misty weather were to be denied us. By 8 A.M. the visibility was extreme, as they say in meteorological circles; one's horizontal range of vision from shipboard was only limited by one's height of eye above the level of the sea. This condition, to say the least of it, was disconcerting. It would be high tide at Zeebrugge and Ostende soon after midnight. Arrival at such an hour would {166} entail making much of the oversea passage in broad daylight, and this, as previously mentioned, would in turn lead to grave risk of being seen by the German patrols, whether the latter were in the air, on the sea surface, or submerged keeping periscope watch. Although this disadvantage might even lose us the element of surprise on which we had concentrated so much effort, any postponement of our departure until the morrow would entail a reduction of our available period by one-seventh. The armchair critic who knows nought of such matters cannot easily conceive either the difficulty of arriving at such decisions, or the weight of responsibility which lies on the shoulders of the man by whom the decision must be given. Early in the forenoon it was evident that all conditions except visibility were in favour of starting our third attempt. Our hopes ran high in spite of the fact that previous experience had shown us how fickle the weather could be. Somehow we felt that our chance had come at last.
