Remember the Maine Day is observed annually on February 15 in remembrance of the U.S. battleship, U.S.S. Maine, which sank in Havana Harbor after a mysterious explosion, resulting in the deaths of 266 crew members. The incident occurred in 1898 during the Cuban War of Independence and led to significant political turmoil, including a naval blockade and a declaration of war against Spain. The cause of the explosion remains officially unknown, but the U.S. Naval Court of Inquiry suggested a mine was responsible, which fueled public outrage and anti-Spanish sentiment. Slogans like “To hell with Spain, Remember the Maine” became popular as Americans rallied in response to the tragedy. This day serves as a solemn reminder of the lives lost while serving their country and is marked by commemorations honoring the bravery of those who perished.
