On 30 July 1916, German saboteurs blew up a Jersey City munitions depot, scarring the Statue of Liberty and stopping a clock a mile away. Washington dismissed it as a regrettable accident. It took the United States another year to call it what it was.

The Man Who Kept One Eye

Jul 29, 2026By Andy Barca

On 29 July 1014, Basil II crushed the Bulgarian army at Kleidion and blinded thousands of prisoners, leaving one man in every hundred a single eye to lead the rest home. The battle didn't decide the war. The punishment decided how we'd remember it.

On 28 July 1942, with the Wehrmacht driving on Stalingrad, Stalin issued Order No. 227: retreat without written orders, and face a penal battalion, the Gulag, or a bullet from your own side. It may have helped save the front. That is not the same as justifying it.

On 26 July 1529, the Spanish crown named Francisco Pizarro governor of a country Spain did not yet control. The illegitimate, illiterate son of an infantry officer had talked his way into ruling an empire he had only glimpsed from a boat - and shortchanged the partner who had helped him find it.

On 25 July 1467, cannon and hand-guns decided a battle in Italy for the first time, at Molinella near Bologna. The condottieri's genteel, low-casualty way of war - fought for ransom, not for blood - did not survive the encounter.
