That was a long and wretched night.

Morning found him still strong physically, but in a dreadful state of mind.
First he hurried for the river.

He could withstand the pangs of hunger, but it was imperative to quench thirst.

His wound made him feverish, and therefore more than usually hot and thirsty.

Again he was refreshed.
That morning he was hard put to it to hold himself back from attempting to cross the river.
