All the while I looked out over the sea, and then I saw something else that I could not at first make out.
Somewhere on the sea, right off the mouth of the Watchet haven, and seemingly close under me, there flashed brightly a light for a moment and instantly, far out in the open water another such flash answered it -- seen and gone in an instant.

Then came four more such flashes, each a little nearer than the second, and from different places.

Then I found that the first and one other near it were not quite vanished, but that I could see a spark of them still glowing.
Now while I wondered what this might mean, those two nearer lights began to creep in towards the haven, closer and closer, and as they did so, flashed up again, and answering flashes came from the other places.
The night was still, and I sat down to see more or this, knowing that they who made these signals must be in ships or boats; but not knowing why they were made, or why so many ships should be gathered off the haven.

Anyway there would be many people about to meet them if they came in, and that would not suit me.
Then all of a sudden the light from the nearest ship flamed up, bright and strong, and moved very fast towards the haven, and the others followed, for first one light and then another came into sight like the first two as they drew near.

I knew not much about ships, but it seemed to me as if lanterns were on deck, and hidden from the shore by the bulwarks, perhaps, but that being so high above, I could look down on them.
"If they be honest vessels," thought I, all of a sudden, "why do they hide their lights ?" for often had I seen the trading busses pass up our Parret river at night with bright torches burning on deck.
What was that?
Very faint and far away there came up to me in the still air, for what breeze there was set from the sea to me, a chant sung by many rough voices--a chant that set my blood spinning through me, and that started me to my feet, running with all the speed I could make in the darkness to warn Watchet town that the vikings were on them! For now I knew.
