What Happened That Day?

Faunce wanted to know everything. One of the local who was now very old even told him that he did see a man surviving the crash and running into the forest with a whole army behind him. Despite the fact he was heavily injured he kept running till his last breath. When there was nothing left inside his body, he collapsed. The army surrounded him with their guns and legs poking him to see if he was alive. The army could see a man crying in pain but his body was so weak that no sound came out from his mouth. After listening to the old man’s story Faunce could feel his legs shaking and goosebumps on his body. What happened to Robertson?
