The Lusitania disaster not only resulted in tragic loss of life but also led to significant changes in naval policy. After the attack, two British cruisers that paused to rescue survivors became easy targets for U-boats, highlighting the dangers of such humanitarian efforts during wartime. This incident prompted a reevaluation of naval strategy and priorities.

In response to the vulnerability demonstrated by the cruisers, the Admiralty issued new directives that prohibited large British warships from assisting victims of U-boat attacks. This shift underscored the strategic importance of protecting military assets over humanitarian concerns, reflecting the harsh realities of naval warfare during that period.
