"This was especially true of the navy sailors under Rommel's charge. Since the Versailles Treaty had forbidden the Germans from maintaining a navy, these sailors were now army men. Butler records a story in which Rommel, derided by his men for wearing his World War I medals, replied by telling them of his prayers for them during his evenings at the front: "My prayers were heard, because here you are." As Rommel would later write in his Infantry Attacks, "Winning the men's confidence requires much of a commander. He must exercise care and caution, look after his men, live under the same hardships, and--above all--apply self-discipline. But once he has their confidence, his men will follow him through hell and high water."[35] This was certainly true in Rommel's life, and the former sailors gave Rommel no more trouble."
