Draw the blanket of the ocean

Convoy
by Charles Causley

Draw the blanket of ocean
over the frozen face.
He lies, his eyes quarried by glittering fish,
Staring through the green freezing sea-glass
At the Northern Lights.

He is now a child in the land of Christmas:
Watching, amazed, the white tumbling bears
And the diving seal.
The iron wind clangs round the ice-caps,
The five-pointed Dog-star
Burns over the silent sea.

And the three ships
Come sailing in.
