She was a floating fortress, with men enough to make up the population of a town, and with stores, ammunition, and coal sufficient to last for a long term of active service. Such was the mighty English battleship which had come forward to raise the siege of the Canadian port. The officers of the Syndicate were well aware of the character of the Adamant, her armament and her defences, and had been informed by cable of her time of sailing and probable destination. They sent out Repeller No. 7, with Crabs J and K, to meet her off the Banks of Newfoundland. This repeller was the largest and strongest vessel that the Syndicate had ready for service. In addition to the spring armour with which these vessels were supplied, this one was furnished with a second coat of armour outside the first, the elastic steel ribs of which ran longitudinally and at right angles to those of the inner set. Both coats were furnished with a great number of improved air-buffers, and the arrangement of spring armour extended five or six feet beyond the massive steel plates with which the vessel was originally armoured. She carried one motor-cannon of large size. One of the crabs was of the ordinary pattern, but Crab K was furnished with a spring armour above the heavy plates of her roof. This had been placed upon her after the news had been received by the Syndicate that the Adamant would carry a perpendicular cannon over her stern, but there had not been time enough to fit out another crab in the same way. When the director in charge of Repeller No. 7 first caught sight of the Adamant, and scanned through his glass the vast proportions of the mighty ship which was rapidly steaming towards the coast, he felt that a responsibility rested upon him heavier than any which had yet been borne by an officer of the Syndicate; but he did not hesitate in the duty which he had been sent to perform, and immediately ordered the two crabs to advance to meet the Adamant, and to proceed to action according to the instructions which they had previously received. His own ship was kept, in pursuance of orders, several miles distant from the British ship. As soon as the repeller had been sighted from the Adamant, a strict lookout had been kept for the approach of crabs; and when the small exposed portions of the backs of two of these were perceived glistening in the sunlight, the speed of the great ship slackened. The ability of the Syndicate's submerged vessels to move suddenly and quickly in any direction had been clearly demonstrated, and although a great ironclad with a ram could run down and sink a crab without feeling the concussion, it was known that it would be perfectly easy for the smaller craft to keep out of the way of its bulky antagonist. Therefore the Adamant did not try to ram the crabs, nor to get away from them. Her commander intended, if possible, to run down one or both of them; but he did not propose to do this in the usual way.
