Clearly enough, it would be somewhat futile if one only began to consider the work of demolition as soon as the moment arrived for such work to commence. With the object of being prepared in all respects careful consideration, therefore, was given to the different methods of demolition which would be most suitable under varying circumstances. Following such consideration it would be necessary to train one's demolition parties in this technical pursuit and to provide a sufficiency of suitable destructive material. [Sidenote: Plans for Demolition] When making preparations for an operation of this, or similar type, one is apt to allow secondary objects to loom too large unless great caution is taken to prevent it. In this particular case, however correct it might be to fully prepare, down to the smallest detail, for everything in advance, it was necessary to bear in mind that demolition on the Mole could hardly assist the blockships to seal the canal exit and, even if successful, could not bring us very great benefit. Thus it was clear that demolition should only be prepared for and undertaken provided that it did not hinder the attainment of our main object in the smallest particular. H.M.S. _Vindictive_ had to be fitted with a special deck from which gangways could be extended to bridge the gulf between the ship and the top of the twenty-nine-foot wall. For this purpose she was given {78} a large number of gangways poised at an angle of about forty-five degrees from the ship's side. The idea was that on arriving alongside the Mole, the gangways would be lowered till they rested on the top of the wall. The storming parties, at a prearranged signal, should run out along the gangways and jump down to the parapet pathway four feet below the wall top. They should then get across the pathway, over the iron handrails on its inner side, down to the floor level of the Mole, sixteen feet below, and then start the work. Now, one cannot expect men carrying all their accoutrements and paraphernalia, such as rifles, machine-guns, flame-throwers, bombs and grenades, rifle and gun ammunition, and such-like to jump down a drop of sixteen feet on to a stone surface. So it was arranged that the advanced storming parties should carry long storming ladders to place against the wall on its inner side and thus facilitate access to the floor level. Seamen were to land first, both for the purpose just stated and for securing the ship to the Mole after the _Vindictive_ had been pushed alongside the Mole by another vessel. [Illustration: H.M.S.
