I had seen both, looking at us round the stem of a cocoa-nut tree, where the moon struck them. I had seen that Sambo Pilot, with one hand laid on the stem of the tree, drawing them back into the heavy shadow. I had seen their naked cutlasses twinkle and shine, like bits of the moonshine in the water that had got blown ashore among the trees by the light wind. I had seen it all, in a moment. And I saw in a moment (as any man would), that the signalled move of the pirates on the mainland was a plot and a feint; that the leak had been made to disable the sloop; that the boats had been tempted away, to leave the Island unprotected; that the pirates had landed by some secreted way at the back; and that Christian George King was a double-dyed traitor, and a most infernal villain. I considered, still all in one and the same moment, that Charker was a brave man, but not quick with his head; and that Sergeant Drooce, with a much better head, was close by. All I said to Charker was, "I am afraid we are betrayed. Turn your back full to the moonlight on the sea, and cover the stem of the cocoa-nut tree which will then be right before you, at the height of a man's heart. Are you right?" "I am right," says Charker, turning instantly, and falling into the position with a nerve of iron; "and right ain't left. Is it, Gill?" A few seconds brought me to Sergeant Drooce's hut. He was fast asleep, and being a heavy sleeper, I had to lay my hand upon him to rouse him. The instant I touched him he came rolling out of his hammock, and upon me like a tiger. And a tiger he was, except that he knew what he was up to, in his utmost heat, as well as any man. I had to struggle with him pretty hard to bring him to his senses, panting all the while (for he gave me a breather), "Sergeant, I am Gill Davis! Treachery! Pirates on the Island!" The last words brought him round, and he took his hands of. "I have seen two of them within this minute," said I. And so I told him what I had told Harry Charker. His soldierly, though tyrannical, head was clear in an instant. He didn't waste one word, even of surprise. "Order the guard," says he, "to draw off quietly into the Fort." (They called the enclosure I have before mentioned, the Fort, though it was not much of that.) "Then get you to the Fort as quick as you can, rouse up every soul there, and fasten the gate. I will bring in all those who are at the Signal Hill. If we are surrounded before we can join you, you must make a sally and cut us out if you can. The word among our men is, 'Women and children!'" He burst away, like fire going before the wind over dry reeds. He roused up the seven men who were off duty, and had them bursting away with him, before they know they were not asleep. I reported orders to Charker, and ran to the Fort, as I have never run at any other time in all my life: no, not even in a dream.
