Stand by the Union by Oliver Optic

Lieutenant Christopher Passford, in his two years' experience in the navy, had been under the fire of the enemy too many times to be intimidated by a burglar, and he felt a certain contempt for the midnight marauder, who had entered the mansion and disturbed his restful slumbers. He returned to his bed, therefore, and slept like a marine till the call bell woke him in the morning.

As he dressed himself he could not help thinking of the mysterious visitation, and he asked himself a great many questions in regard to the object of the intruder, since it did not appear that he had entered the house for the purpose of robbing its occupants. He could not determine whether or not the fellow had actually come into his room; but his porte-monnaie, which contained a considerable sum of money, and his gold repeater, a very valuable watch, were just where he had left them the night before.
