The Garrison That Mistook an Attack for a Salute

Listen to this episode

10 min

This incident highlights how drastically miscommunications can alter the course of history, while also showing the sometimes courteous nature of conflict.

Picture this: you’re the commander of a Spanish garrison, minding your business, when an American warship sails into your harbour and unleashes a furious round of cannon fire. Naturally, you assume this is a salute and send a gentlemanly apology for your lack of firepower to return the gesture. Thus begins one of history’s most courteous military surrenders.

On 21 June 1898, the USS Charleston arrived at Fort Santa Cruz in Guam, under the impression that hostilities in the Spanish-American War were well underway. Meanwhile, the blissfully unaware Spanish garrison on the island had missed the memo entirely. Realising their ammo situation was far from ideal, the garrison sent officers to convey their regrets. Imagine their surprise when Captain Henry Glass informed them that not only was this no friendly salute, but they were also already two months deep into the war. The result? A painless surrender that left everyone unscathed.

History’s Other Left Turns

The tale of Guam’s genteel handover is just one example from the historical grab bag that is 21 June. Fast forward to 1942, when an entirely different type of warfare was making history. On this day, a Japanese submarine emerged off the coast of Oregon and lobbed seventeen shells at Fort Stevens, marking one of the few direct assaults on the continental U.S. American troops? Ordered not to return fire, they watched as confusion reigned supreme once more, albeit without injury.

Skipping ahead to 2004, exchange artillery for feats of human ingenuity. SpaceShipOne soared into space, becoming the first privately funded craft to reach such heights. Pilot Mike Melvill joined the ranks of the elite as a commercial astronaut, setting a new precedent for cosmic adventures with a privately bankrolled ticket.

Then there’s the 2006 christening of Pluto’s moons: Nix and Hydra. Their celestial names were bestowed just weeks before Pluto’s rebranding as a dwarf planet, an amusing touch in the cosmos.

Never underestimate the oddities of 21 June. Whether it’s a war that forgot its own announcement or a viral cat like Lil Bub born to charm the world, history continually reminds us of humanity’s mix of charm, bluster, and boundless curiosity.

Listen to the full episode to explore these captivating moments. History, it seems, has an enduring way of laughing quietly behind its hand at our perpetual blind spots.

  • CTA Invitation to follow the show and share with curious friends.
  • Bombardment of Fort Stevens On 21 June 1942, a Japanese submarine surfaced near the Columbia River and fired seventeen shells at Fort Stevens in Oregon, one of the only direct attacks on the continental United States during the Second World War. American forces were ordered not to return fire, and no one was killed.
  • SpaceShipOne On 21 June 2004, SpaceShipOne became the first privately funded spacecraft to reach the edge of space, crossing the Kármán line at roughly 100 kilometres altitude. Pilot Mike Melvill became the first commercial astronaut, and the craft later won the Ansari X Prize.
  • Pluto’s Moons Named Nix and Hydra On 21 June 2006, two of Pluto’s moons received official names: Nix and Hydra, both from Greek mythology and conveniently matching the initials of the New Horizons spacecraft. This occurred weeks before Pluto was reclassified as a dwarf planet.
  • Lil Bub On 21 June 2011, Lil Bub was born in Indiana. The cat, born with genetic mutations that gave her a distinctive appearance, became an internet sensation and raised significant funds for animal rescue charities before her death in 2019.
