What "crime" is Henry unable to conceal in Chapter 10?

Henry is unable to conceal the fact that he is not wounded..... he committed the crime of running away from battle.

""Yeh look pretty peek'ed yerself," said the tattered man at last. "I bet yeh 've got a worser one than yeh think. Ye'd better take keer of yer hurt. It don't do t' let sech things go. It might be inside mostly, an' them plays thunder. Where is it located?""

"The youth had been wriggling since the introduction of this topic. He now gave a cry of exasperation and made a furious motion with his hand. "Oh, don't bother me!" he said."

"The simple questions of the tattered man had been knife thrusts to him. They asserted a society that probes pitilessly at secrets until all is apparent. His late companion's chance persistency made him feel that he could not keep his crime concealed in his bosom. It was sure to be brought plain by one of those arrows which cloud the air and are constantly pricking, discovering, proclaiming those things which are willed to be forever hidden. He admitted that he could not defend himself against this agency. It was not within the power of vigilance."
