Paul. Stesman is such an engineer. Although he didn't want to join the army, his background as an architect made him an engineer. Whenever he needs to cross the river, he should organize a bridge in front of the vanguard. The following is the story of Stesman's first bridge construction under the enemy's artillery fire: "We took wood and rode in a rubber boat, and all kinds of guns came at us. Even when our own people shot at the Polish army hidden in the ruins of trees or villages, we felt very scared. We rushed to the middle of the river and tied the floating trunk and raft with many ropes to build a pontoon bridge. "

"At this time, the dust caused by bombs and guns is flying overhead. After our infantry crossed the river, we must build a stronger bridge for the tank. But when we first entered the deep water, a machine gun opened fire on us and the nearest person was killed. I saw him fall into the water and float away, but there was nothing I could do. We jumped into the water and grabbed the side of the rubber boat. These rubber boats have been perforated in some places and are being scrapped bit by bit. I don't know how long it took, but I was so scared that I could hardly speak. There is only a loud noise in my ear. "

"After a while, the enemy's firepower gradually weakened, and I knew it must be our dive plane to pick up the enemy. We continued to build the bridge and finally built a bridge that soldiers could cross. As soon as we put the last board away, the soldiers rushed to the bridge and crossed the river quickly. "

"At that time, I looked around and found that our commander and several other people were gone. How difficult it is for us field engineers to build a pontoon bridge in the face of the fierce attack of the enemy! "
