The rearmost of the American aviators had looked back, had seen the first of the aero-subs drop down among the doomed ships.

The Americans were wary. They drew together like frightened chickens when a hawk hovers above them, and watched the activities of the aero-subs, every move of each one being at the same time visible and audible to the Secret Agents in the Capitol's Secret Room.
The aero-subs which had submerged singled out their particular prey among the floating ships, and the Secret Agents, trying to see how each separate act of destruction was accomplished, watched the aero-sub in the foreground, which happened to be concentrating on the dreadnought which had led the ghost-march of the warships out to sea.
