Then it was, with the train running forty miles an hour, that he jumped to his feet and dived through the little car window. He landed on his head and knees on the opposite track. Although badly stunned, he struggled to his feet and began to run. By this time the train had been stopped and the guards were pursuing, firing as they came on. Isaacs went some distance but could hardly run for he had badly injured his knees. A bullet whistled by his ear and he dropped and let the guard come up to him. Mad with rage the German kicked him, and beat him with his gun until he broke it. The rest of the guards soon came up. Then they made Isaacs walk the five miles into Baden, beating him now and then on the way. On reaching the camp he was first taken to the officers' quarters and threatened with death if he tried again to escape. After being plastered with paper bandages he was put into solitary confinement for three weeks. So poor was the prison food that had it not been for the nourishment furnished by the American Red Cross, Isaacs never would have recovered. He had been threatened with death if he tried again to escape, but he began at once to make plans and would have gained his liberty much sooner than he did, had not the Russian prisoner attendants each time betrayed his plans before he could try them. And now he and Lieutenant Willis with fourteen other men decided to try again for freedom. The prisoners were sometimes permitted to take walks with the guards about the country. In this way the men who were to escape were able to learn about the roads and the best hiding places. They managed to secure maps and compasses by bribing some of the Russian attendants. But these would only be of help when once outside the camp, and how to get out was a serious question. Some believed that the best way was to get past the guards through the big gate. To climb over the two wire fences, so heavily charged with electricity, seemed entirely impossible. But Isaacs discovered a way across that barbed wire. He had seen two of the prisoners marking out the whitewashed lines on the tennis court where the German officers played each day. The lines were made by the use of two narrow wooden boards, eighteen feet long, fastened together by crosspieces, allowing a small space of about two inches between. While the boards seemed very light, they were so fastened together that they were really quite strong. They could be made even stronger by nailing on more cross-pieces. Then they would form a sort of bridge over which the men could crawl from the barracks' windows to the outer fence, where they could drop to the ground and run from the sentinels.
