Taking everything into consideration and looking at the operation of attacking the Mole from a general point of view, it was not dissimilar to a trench raid on a large scale. The preparatory bombardment, the rush "over the top," the probability of encountering barbed wire, the descent to the main level of the Mole, the hand-to-hand fighting in the dark, and {113} finally the clearing of dug-outs, all combined to liken that phase of the operation to one of the many night raids with which the military were so well acquainted on the western front. The senior officers of the Seamen and Marine storming parties had both gained much experience of such fighting ashore. It was to be a raid of the first water, a super-raid. The military officers were most enthusiastic about our men. They declared that these men could carry any position. For they were all picked men; and even so some of them were weeded out as not quite reaching high-water mark at the game. It was generally conceded that the Hun, wherever he was to come to close quarters with such antagonists, would have an uncomfortable evening. It has been mentioned above that special personnel were not required for the large majority of vessels which were already in full commission and employed on active duty in the Dover Command. The personnel required for the blockships and storming vessels and for other special purposes amounted to eighty-six officers and sixteen hundred and ninety-eight men; of these, seven hundred and fifty, in the aggregate, were drawn from the Royal Marines.
