In Erik Larson's book "Dead Wake: The Last Crossing of the Lusitania," the narrative delves into the events surrounding the sinking of the Lusitania during World War I. One of the notable figures discussed is Admiral Henry Francis Oliver, who served as the chief of staff for the Admiralty. His reserved and taciturn nature earned him the nickname "Dummy" Oliver, reflecting the British navy's penchant for playful nicknames.

The portrayal of Oliver highlights an intriguing aspect of naval life and communication during a tumultuous period. This nickname symbolizes not only his personality but also the culture within the British navy, illustrating how relationships and reputations were shaped by behavior and interactions, especially during critical times of conflict.
