“ ‘Doing?’ I cried. ‘Why, they’re going to blow up the bridge! And we must save it. But how?’
“I looked around, but there was unfortunately no one in the immediate vicinity. I had no weapon, but the fellows were no doubt armed and desperate. Into the dark police office I peered, but could see nothing. Then suddenly an idea occurred to me. If I raised the alarm at that moment, they would certainly escape. Both Frank and I could row, therefore I sprang into the police boat at the pier, unmoored her, and urged my son to take an oar with me. In less time than it takes to relate we had pulled across into the shadow of the big arch, and were alongside the empty boat of the conspirators.
“ ‘Row away for your life!’ I cried to Frank, as I sprang into the other boat. Then taking out my knife I cut her adrift in an instant and pulled out hard with the tide towards Cleopatra’s Needle, while Frank, grasping my intention, shot away towards the Surrey bank. Scarce had I taken out my knife to sever the cord, however, than the three men above noticed me and shouted down in broken English. Indeed, as I pulled off there was the sharp crack of a revolver above me, and I think I narrowly escaped being winged. Nevertheless, I had caught the three blackguards in a trap. The explosive had already been fixed to the crown of the arch, but if they lit the fuse they must themselves be blown to atoms.
“I could hear their shouts and curses from where I rested upon my oars, undecided how to act. If I could only have found at that moment a couple of those brave ‘Frontiersmen’ or ‘Britons,’ or members of rifle clubs, who had been such trouble to the enemy out in Essex! There were hundreds upon hundreds of them in London, but they were in the streets still harassing the Germans wherever they could. I rested on my oars in full view of the spies, but beyond revolver range, mounting guard upon them, as it were. They might, after all, decide to carry out their evil design, for if they were good swimmers they might ignite the fuse and then dive into the water, trusting to luck to get to the steps around Cleopatra’s Needle. Would they dare do this?
“They kept shouting to me, waving their hands excitedly; but I could not distinguish what they said, so great was the din on the bridge above. Frank had disappeared. Whither he had gone I knew not. He had, however, seen the revolver fired at me, and recognising what was taking place would, I felt certain, seek assistance. One of the men descending the ladder to the water, shouted again to me, waving his hand frantically and pointing upward. From this I concluded that he intended to convey that the time-fuse was already ignited and they were begging for their lives to be saved. Such men are always cowards at the supreme moment when they must face death. I saw the fellow’s pale, black-bearded face in the shadow, and an evil, murderous countenance it was, I assure you. But to his shouts, his threats, his frantic appeals I made no response. I had caught all three of them, and paused there triumphant. Would Frank ever return? Suddenly, however, I saw a boat in the full light out in the centre of the river, crossing in my direction, and hailed it frantically. The answering shout was my boy’s, and as he drew nearer I saw that with him were four men armed with rifles. They were evidently four Freeshooters who had been in the roadway above to hold the bridge against the enemy’s advance!
“With swift strokes of the oars Frank brought the police boat up alongside mine, and in a few brief sentences I explained the situation and pointed to the three conspirators.
“ ‘Let’s shoot them from where we are!’ urged one of the men, who wore the little bronze badge of a Frontiersman, and without further word he raised his rifle and let fly at the man clinging to the ladder. The first shot went wide, but the second hit, for with a cry the fellow released his hold and fell back into the dark tide, his lifeless body being carried in our direction.
“The other three men in the boat, members of the Southfields (Putney) Rifle Club, opened a hail of fire upon the pair hidden in the scaffolding above. It was a dangerous proceeding, for had a stray bullet struck that case full of explosives, we should have been all blown to atoms in an instant. Several times all four emptied their magazines into that semicircular opening, but to no effect. The fusilade from the river quickly attracted the attention of those above, to whom the affair was a complete mystery. One rifleman upon the bridge, thinking we were the enemy, actually opened fire upon us; but we shouted who we were, and that spies were concealed below, whereupon he at once desisted.
“A dozen times our party fired, when at last one man’s dark body fell heavily into the stream with a loud splash; and about a minute later the third fell backwards, and the rolling river closed over him. All three had thus met with their well-merited deserts.
“ ‘I wonder if they’ve lit the fuse?’ suggested one Frontiersman. ‘Let’s go nearer.’
