A few days later the same sentinel, who had been called a blockhead for raising a false alarm, again heard Trenck burrowing, and called his comrades. The major came also to hear the noise, and it was now realised that Trenck was working under the foundation toward the gallery. The officials entered the gallery at the other end with lanterns, and Trenck as he crawled along saw the light and their heads. He knew the worst, and hurrying back to his cell, had still the presence of mind to conceal his pistols, candles, paper and money in various holes and hiding places, where they were never found. This was barely accomplished before his guards arrived, headed by the brutal and stupid major, Bruckhausen by name. The hole in the floor was at once filled up and the planking reinstated; his foot-chains, instead of being merely fastened as before, were screwed down and riveted. The worst trial for the moment was the loss of his bed, which he had cut up to make into bags for the removal of the sand. At this time General Borck was ill with an ailment that soon ended in mental derangement. Another general, Krusemarck, replaced him and proceeded to visit Trenck. They had been old friends and brother officers, but the general showed him no compassion; on the contrary, he abused him roundly, promising him even more severe treatment. It was then that the inhuman order was issued to the night guards to waken Trenck every quarter of an hour,--a devilish form of cruelty unsurpassed in prison punishments. Kindly nature, however, came to the rescue, and Trenck learned to answer automatically in his sleep; yet this cruel device was continued for four years and until within a few months of his final release.
