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. From all over Middlesex, and more especially from the London area, came sensational reports of the drastic measures adopted by the Germans to repress any sign of revolt. In secret, the agents of the League of Defenders were at work, going from house to house, enrolling men, arranging for secret meeting-places, and explaining in confidence the programme as put forward by the Bristol committee. Now and then, however, these agents were betrayed, and their betrayal was in every case followed by a court-martial at Bow Street, death outside in the yard of the police station, and the publication in the papers of their names, their offence, and the hour of the execution. Yet, undaunted and defiantly, the giant organisation grew as no other society had ever grown, and its agents and members quickly developed into fearless patriots. It being reported that the Saxons were facing Lord Byfield with the Thames between them, the people of West London began in frantic haste to construct barricades. The building of obstructions had, indeed, now become a mania north of the river as well as south. The people, fearing that there was to be more fighting in the streets of London, began to build huge defences all across West London. The chief were across King Street, Hammersmith, where it joins Goldhawk Road, across the junction of Goldhawk and Uxbridge Roads, in the Harrow Road where it joins Admiral Road, and Willesden Lane, close to the Paddington Cemetery, and the Latimer Road opposite St. Quintin Park Station. All the side streets leading into the Goldhawk Road, Latimer Road, and Ladbroke Grove Road were also blocked up, and hundreds of houses placed in a state of strong defence. With all this Von Kronhelm did not interfere. The building of such obstructions acted as a safety-valve to the excited populace, therefore he rather encouraged than discountenanced it. The barricades might, he thought, be of service to his army if Lord Byfield really risked an attack upon London from that direction. Crafty and cunning though he was, he was entirely unaware that those barricades were being constructed at the secret orders of the League of Defenders, and he never dreamed that they had actually been instigated by the British Commander-in-Chief himself. Thus the Day of Reckoning hourly approached, and London, though crushed and starving, waited in patient vigilance.
