Everywhere the walls of South London were placarded with manifestoes of the League of Defenders. Day after day fresh posters appeared, urging patience and courage, and reporting upon the progress of the League. The name of Graham was now upon every one's lips. He had, it seemed, arisen as saviour of our beloved country. Every word of his inspired enthusiasm, and this was well illustrated at the mass meeting on Peckham Rye, when, beneath the huge flag of St. George, the white banner with the red cross—the ancient standard of England—which the League had adopted as theirs, he made a brilliant and impassioned appeal to every Londoner and every Englishman.
Report had it that the Germans had set a price upon his head, and that he was pursued everywhere by German spies—mercenaries who would kill him in secret if they could. Therefore he was compelled to go about with an armed police guard, who arrested any suspected person in his vicinity. The Government, who had at first laughed Graham's enthusiasm to scorn, now believed in him. Even Lord Byfield, after a long council, declared that his efforts to inspire enthusiasm had been amazingly successful, and it was now well known that the "Defenders" and the Army had agreed to act in unison towards one common end—the emancipation of England from the German thraldom.
Some men of the Osnabrück Regiment, holding Canning Town and Limehouse, managed one night, by strategy, to force their way through the Blackwall Tunnel and break down its defences on the Surrey side in an attempt to blow up the South Metropolitan Gas Works.
The men holding the tunnel were completely overwhelmed by the number that pressed on, and were compelled to fall back, twenty of their number being killed. The assault was a victorious one, and it was seen that the enemy were pouring out, when, of a sudden, there was a dull, heavy roar, followed by wild shouts and terrified screams, as there rose from the centre of the river a great column of water, and next instant the tunnel was flooded, hundreds of the enemy being drowned like rats in a hole.
The men of the Royal Engineers had, on the very day previous, made preparations for destroying the tunnel if necessary, and had done so ere the Germans were aware of their intention. The exact loss of life is unknown, but it is estimated that over 400 men must have perished in that single instant, while those who had made the sudden dash towards the Gas Works were all taken prisoners, and their explosives confiscated.
The evident intention of the enemy being thus seen, General Sir Francis Bamford, from his headquarters at the Crystal Palace, gave orders for the tunnels at Rotherhithe and that across Greenwich Reach, as well as the several "tube" tunnels and subways, to be destroyed, a work which was executed without delay, and was witnessed by thousands, who watched for the great disturbances and upheavals in the bed of the river.
In the Old Kent Road the bridge over the canal, as well as the bridges in Wells Street, Sumner Road, Glengall Road, and Canterbury Road, were all prepared for demolition in case of necessity, the canal from the Camberwell Road to the Surrey Dock forming a moat behind which the defenders might, if necessary, retire. Clapham Common and Brockwell Park were covered with tents, for General Bamford's force, consisting mostly of auxiliaries, were daily awaiting reinforcements.
Lord Byfield, now at Windsor, was in constant communication by wireless telegraphy with the London headquarters at the Crystal Palace, as well as with Hibbard on the Malvern Hills and Woolmer at Shrewsbury. To General Bamford at Sydenham came constant news of the rapid spread of the national movement of defiance, and Lord Byfield, as was afterwards known, urged the London commander to remain patient, and invite no attack until the League were strong enough to act on the offensive.
Affairs of outpost were, of course, constantly recurring along the river bank between Windsor and Egham, and the British Free-shooters and Frontiersmen were ever harassing the Saxons.
Very soon Von Kronhelm became aware of Lord Byfield's intentions, but his weakness was apparent when he made no counter-move. The fact was that the various great cities he now held required all his attention and all his troops. From Manchester, from Birmingham, from Leeds, Bradford, Sheffield, and Hull came similar replies. Any withdrawal of troops from either city would be the signal for a general rising of the inhabitants. Therefore, having gained possession, he could only now sit tight and watch.
