They came out and went back on to the path where the trees might possibly make them
less conspicuous. "Not that it's any good really," said Eustace, "trying to hide from people
you can't see. They may be all round us."
"Now, Drinian," said Caspian. "How would it be if we gave up the boat for lost, went
down to another part of the bay, and signalled to the Dawn Treader to stand in and take
us aboard?"
"Not depth for her, Sire," said Drinian.
"We could swim," said Lucy.
"Your Majesties all," said Reepicheep, "hear me. It is folly to think of avoiding an
invisible enemy by any amount of creeping and skulking. If these creatures mean to bring
us to battle, be sure they will succeed. And whatever comes of it I'd sooner meet them
face to face than be caught by the tail."
"I really think Reep is in the right this time," said Edmund.
"Surely," said Lucy, "if Rhince and the others on the Dawn Treader see us fighting on the
shore they'll be able to do something."
"But they won't see us fighting if they can't see any enemy," said Eustace miserably.
"They'll think we're just swinging our swords in the air for fun."
There was an uncomfortable pause.
"Well," said Caspian at last, "let's get on with it. We must go and face them. Shake hands
all round - arrow on the string, Lucy - swords out, everyone else - and now for it. Perhaps
they'll parley."
It was strange to see the lawns and the great trees looking so peaceful as they marched
back to the beach. And when they arrived there, and saw the boat lying where they had
left her, and the smooth sand with no one to be seen on it, more than one doubted whether
Lucy had not merely imagined all she had told them. But before they reached the sand, a
voice spoke out of the air.
"No further, masters, no further now," it said. "We've got to talk with you first. There's
fifty of us and more here with weapons in our fists."
"Hear him, hear him," came the chorus. "That's our Chief. You can depend on what he
says. He's telling you the truth, he is."
"I do not see these fifty warriors," observed Reepicheep.
