Simile: "They knelt in the woods, as if it had been a cathedral"
The trees are likened to a cathedral in two ways: first, the arch of the trees points heavenward and inspires them to prayer; second, the trees are leafless and arch overhead, effecting the same gothic style as old churches and cathedrals.
Simile: "A heavy mist hung over the valley so thick it was like a white blanket which parted only enough for the next step to be seen"
Here, the mist is extremely low and, rather than being in the air, it actually seems to be like a heavy piece of fabric that prevents the travelers from seeing more than the length of a stride in front of them. This description brings an air of mystery and danger to the scene, as the men do not know what they will encounter next.
Metaphor: "Robin's face was drawn into a black cloud of anger"
When Robin accidentally drops his chisel and ruins his cross, he becomes quite upset. Although he is usually a good-natured boy, he is frustrated to have his work destroyed, and the quick shift of his mood is illustrated by the "black cloud" that overcomes his face.
Simile: "From where they stood Robin could see it all as plainly as if it had been a toy village set in a toy landscape, and the soldiers, toy soldiers."
Robin is at the top of the church tower with John, peering down at the armies after they have signaled the attack. Because of his great vantage point, the soldiers look like toys, which contrasts with the seriousness of the action taking place.
Simile: "His chest felt tightly squeezed, as if sharp knives pierced him"
When Robin first jumps into the river, the water is so cold that it seems to slice right through him, like very sharp blades cutting into his skin. At this moment, Robin shows his bravery and willingness to leave behind what is comfortable and even endure something painful for a higher cause.
