Not many British queens have also served as daring emergency rescuers. But when the moment arose, Queen Victoria was ready to save the day. In 1841, she saved her husband, Prince Albert, from an icy lake he had fallen into while skating.

The incident didn't need much dramatization when it was included in an episode of the PBS drama Victoria. It really was a life-or-death situation, and 21-year-old Victoria was the hero.

On a cold February day in 1841, Victoria and Albert, who had married almost exactly a year earlier, went for a walk around the gardens of Buckingham Palace. Albert, an avid sportsman who loved to skate and play hockey, strapped on his ice skates and headed out onto the lake. In a diary entry, Victoria wrote that the ice was smooth and hard that day—mostly. As he skated toward her, she noticed that the ice around a bridge looked a little thin.

"I, standing alone on the bank," she wrote in her journal that evening, "said, ‘it is unsafe here,' and no sooner had I said this, than the ice cracked, and Albert was in the water up to his head, even for a moment below." By her own telling, Victoria screamed and reached out her arm to him, holding onto her lady-in-waiting, the only attendant present.

Albert grabbed Victoria's arm and she was able to pull him to safety. He had cut his chin and was dripping wet, but returned home, took a hot bath and a nap, and was up a few hours later to socialize when their uncle Leopold (Victoria and Albert were first cousins) came to visit.

"Her Majesty manifested the greatest courage upon the occasion, and acted with the most intrepid coolness," an account of the event that appeared in The Times a few days later proclaimed. "As soon as the Prince was safe on dry land, the queen gave way to the natural emotions of joy and thankfulness at his providential escape."

Albert recounted his side of the experience in a letter to his step-grandmother, Duchess Caroline of Saxe-Gotha-Altenburg. "I was making my way to Victoria, who was standing on the bank with one of her ladies," he described, when "I fell plump into the water, and had to swim for two or three minutes in order to get out. Victoria was the only person with the presence of mind to lend me assistance, her lady being more occupied in screaming for help." (Both the queen's diary entry and the newspaper account give the lady-in-waiting a little more credit, suggesting that she at least served as an anchor for the queen as she reached out to the prince.)

According to The Times, the problem was bird-related. That morning, the groundskeepers in charge of the various waterfowl that called the lake home had broken the ice around the edges of the water so that the birds could drink. By the time the queen and the prince arrived, those spots had frozen over with a deceptively thin layer of ice.

Thanks to Victoria, though, Albert emerged from the incident with little more than a bad cold and went on to live for another 20 years.

Had Albert died that day on the ice, it could have completely changed European history. Victoria and Albert had already had a daughter, and the future King Edward VII was conceived around this time. If Albert had died, seven of Victoria’s children wouldn’t have been born—children who were married to nobles and rulers across Europe (during World War I, seven of their direct descendants were on thrones as king or queen). And if the future Edward VII hadn’t been conceived, Albert died, and everything else remained the same, it’s possible Kaiser Wilhelm II may have become the ruler of both Germany and the United Kingdom.
