What evidence can you find to indicate that Farquhar is experiencing great pain, despite his feelings that he is escaping?

The evidence that Peyton Farquhar is suffering and in great pain, despite the feeling that he is escaping.

"He thought he shouted these words to his hands, for the undoing of the noose had been succeeded by the direst pang that he had yet experienced. His neck ached horribly; his brain was on fire; his heart, which had been fluttering faintly, gave a great leap, trying to force itself out at his mouth. His whole body was racked and wrenched with an insupportable anguish! But his disobedient hands gave no heed to the command."

"They beat the water vigorously with quick, downward strokes, forcing him to the surface. He felt his head emerge; his eyes were blinded by the sunlight; his chest expanded convulsively, and with a supreme and crowning agony his lungs engulfed a great draught of air, which instantly he expelled in a shriek!"

In the above passages, Farquhar experiences supreme pain, feeling it all over his body.  The whole time that he is swimming then running, he is struggling to breathe, dodging bullets, trying to stay ahead of the soldiers who are determined to shoot him dead.

Even though he is daydreaming of the escape, it is rough and painful, it is certainly not an enjoyable daydream for Farquhar.  It is filled with panic, fear and desperation.  The only moment of joy that the daydream brings is when he sees his wife.  Since it was his daydream, he should have been able to hug his wife, but that is not the case in this story.
