Cuba is spiraling into chaos as President Palma announces his resignation and refuses all peace terms proposed by American commissioners William Taft and Bacon. In a defiant letter, Palma declares the conditions 'contrary to my personal dignity' and says he will step down along with his entire cabinet, effectively leaving Cuba without a government. The situation has deteriorated so badly that the United States is mobilizing a massive military force: 1,500 additional Marines are sailing to Cuba this week, joining the 1,500 already there and over 3,000 bluejackets, creating a naval force of about 7,000. Colonel Littleton W.T. Waller has been ordered to Havana immediately to command the Marines. War Department officials are preparing to send 40,000 troops—virtually every available soldier in the regular army except those in the Philippines. Secretary Taft worked until the 'small hours' trying to broker peace, but moderates warn they may 'make war against the Americans' if the Cuban flag is lowered.

This Cuban crisis marks a critical test of the Roosevelt Doctrine and America's new role as a Caribbean policeman following the Spanish-American War. Just four years after Cuba gained independence, the island nation is collapsing back into civil war, forcing the United States to consider its first major military intervention in the hemisphere. This moment would establish the template for American interventionism in Latin America for decades to come, as Theodore Roosevelt grappled with balancing Cuban sovereignty against American strategic interests in the region.

• The Evening Star cost just 2 cents and offered a massive 20-page edition—more than many modern newspapers
• President Palma's resignation letter reveals the personal sting of American mediation: he calls the peace terms contrary to his 'personal dignity and the prestige of the government'
• Secretary Fonts y Sterling was so angry at the American commissioners that he considered sending Secretary Taft a letter telling him 'that Cubans would not fight to be insulted'
• The War Department was bidding on 'several thousand horses and mules to be supplied to the army within fifteen days'—showing how military logistics still depended on animal power
• Marines were being scrambled from posts as far-flung as Culebra, Puerto Rico and San Juan, with some ordered to take 'the first available merchant steamer' from Mobile

• Colonel Littleton W.T. Waller, now commanding the Cuba operation, had previously led Marines in the brutal Philippine-American War, including the controversial march across Samar that decimated his unit
• The Evening Star's headquarters at 11th Street and Pennsylvania Avenue would later become prime Washington real estate—today that location is steps from the White House
• Secretary of War William Howard Taft, trying to negotiate Cuban peace, would become president just three years later, making this crisis valuable executive experience
• The 40,000 troops being prepared for Cuba represented nearly the entire U.S. Army at the time—America's military was still tiny compared to European powers
• Those Marine battalions sailing from Boston and Philadelphia were traveling on converted civilian steamers, as the U.S. Navy still lacked dedicated troop transport vessels
