Göstl was a machine gunner, manning an MG-42, defending his position against an English (possibly Canadian) attack. During heavy fighting he was shot in his left eye. Shrapnel then wounded him in his upper left arm. Undaunted he continued to fire and was then hit in the other eye, which "almost tore his head off". Even then, completely blinded, he continued to return fire from his machine gun post, alone and shooting at what he could hear, as he was completely unable to see anything. He continued to hold out behind his machine gun and received another hit in his right cheek and nose area of his torn-up face. Göstl held until the enemy attack was ultimately repelled, but it is believed that only because of a jam in the machine gun was Göstl's machine gun silenced. His friend Elmar Bonn worked his way forward to him and with the help of some other men was able to bring him back to a safe position, while under fire. Throughout, he "was suffering horrible pain" and was bleeding heavily from the face.
