When Spain Lost Manila Without Knowing Peace Had Been Signed

On August 12, 1898, Spain and the United States signed the Protocol of Peace in Washington, formally ending the Spanish-American War. But in Manila, where the telegraph cable to Hong Kong had been severed months earlier, no one knew the war was over. For the next two days, diplomacy and battle unfolded in two disconnected worlds, setting the stage for the final collapse of Spanish rule in the Philippines. In Madrid, the Duke of Almodóvar del Río, Spain’s Minister of State, spent days trying to save what remained of the empire. Spain’s fleets had already been destroyed at Cavite and Santiago de Cuba, but Almodóvar argued that the Americans occupied only the Cavite naval arsenal and had no claim over Manila or the rest of the colony. President William McKinley refused to compromise. On August 10, Almodóvar instructed Jules Cambon, the French ambassador representing Spain in Washington, to accept the American terms, declaring that Spain yielded only because of the “absolute impossibility of further physical resistance.”

Manila, meanwhile, remained isolated. Since Admiral George Dewey severed the submarine cable in May, Governor-General Fermín Jáudenes could communicate with Madrid only through messages carried by steamship. Inside Intramuros, conditions were worsening. Manuel Sastrón, a Spanish former government official and historian, recorded that more than 13,000 refugees, wounded soldiers, women, and children had crowded into the walled city. Food and clean water were scarce and disease was spreading. Outside, Emilio Aguinaldo’s army maintained its siege while Dewey’s fleet waited in Manila Bay.

Jáudenes knew the situation was hopeless. His concern was no longer victory, but the safety of the civilians inside Intramuros. Spanish authorities feared that Aguinaldo’s troops might enter the city first and take reprisals against its Spanish population.

At four o’clock on August 12, McKinley, Secretary of State William R. Day, and Cambon gathered at the White House to sign the Protocol of Peace. Spain relinquished Cuba, ceded Puerto Rico and Guam, and accepted the temporary American occupation of Manila pending a final treaty. McKinley immediately ordered hostilities suspended. But the message for Manila had to travel through Hong Kong and then by ship. By then, it was already August 13 in the Philippines, and preparations for battle were underway.

Unaware that peace had been signed, Jáudenes proceeded with a secret arrangement negotiated with Dewey and General Wesley Merritt through Belgian Consul Édouard André. Spain would offer token resistance before surrendering, preserving Spanish military honor while avoiding a bloody assault. Crucially, it also ensured that American troops, rather than Aguinaldo’s army, would occupy Manila.

That morning, American warships bombarded Fort San Antonio Abad before U.S. troops advanced. But not every Spanish unit knew of the arrangement. At Blockhouse No. 14, defenders opened genuine fire, and the staged battle became real. Seventeen Americans and 49 Spaniards were killed. Around one o’clock, the white flag rose over Intramuros, and Jáudenes signed the preliminary capitulation at the Ayuntamiento.

Only on August 16 did a vessel arrive from Hong Kong carrying the delayed telegram: peace had already been signed four days earlier. The revelation embittered many Spanish officers. Sastrón later reflected that the men killed on August 13 had died after the war was already over—victims of distance, delayed communication, and military honor.

Jáudenes was later recalled to Madrid and court-martialed, but defended his decision as the only humane course left to him, one that he believed had spared the civilian population from a far bloodier struggle. As a result of this, he was discharged from service and barred from holding any position.

Manila’s fall was therefore more than the last battle of the Spanish-American War. It was the product of an age when diplomacy could move more slowly than armies. By the time peace reached Manila, history had already taken its course. The final shots of Spain’s 333-year rule in the Philippines were fired because the men fighting simply did not yet know the war had ended.
