Spotlight: Mary Henry

After a couple of somewhat negative, politically-charged posts I felt it was time for a happier one. As such, here’s the story of Mary Henry; an all-but-forgotten heroine from the War of 1812. There is not a lot of source material on her and sadly the above portrait is the only image we have of her, but Mary’s story is an example of the extraordinary things ordinary citizens do during times of war.

She was born Mary Madden (c. 1770 to c. 1830) in County Antrim, Ireland. Unfortunately, not much is known about Mary’s early life. Around the age of 20, she met and married a Royal Artillery gunner from County Derry named Dominic Henry in 1790. The two immigrated to British North America when Dominic was shipped to a post in Niagara. In 1803, Dominic retired from the military, became a pensioner, and was appointed the keeper of the first lighthouse on the Great Lakes in the Town of Niagara.

Jump ahead 10 years and Niagara was in the midst of the War of 1812. On May 27, 1813, the Americans had launched an assault on the nearby Fort George and the surrounding area. Known as the Battle of Fort George, it was a showdown between 4,000 American troops and 1,000 British soldiers bolstered by Canadian militia and Indigenous allies. Despite the British defenders being outnumbered around 1:4, they somehow managed to hang on for two days before retreating to the Burlington Heights (now in Hamilton).

Mary had a front row seat for the battle, but she did not sit around though. Instead, Mary repeatedly walked right through the battlefield and brought food and coffee to the troops, in addition to treating the wounded. Mind you, this was a high casualty fight as the Americans brought 80 cannons with them to cover their landing and soldiers compared the heavy bombardment of the battlefield to a “hailstorm.” Mary was undeterred and kept going back again and again to help out the soldiers. A chronicler described her actions as follows:

“Suddenly they saw a vision. Walking calmly through the shower of iron hail came Mary Madden Henry with hot coffee and food, seemingly as unconcerned as if she were in her own small garden on the shore on a Summer evening before peace was shattered. Time and again she went and came back with more sustenance, apparently guarded by some unseen angel from the peril which menaced her every step. Through the day until darkness brought respite she was caterer and nurse, the only woman in the company to bind the wounds of those maimed in the fight. These who survived never forgot that day, nor the courage of Mary Henry.”

After the battle, the Americans held onto the area until December. They had hoped to use Fort George launch an attack on the British base at Burlington Heights, but their defeat at the Battle of Stoney Creek and Beaver Dams wrecked those plans. Moreover, occupying Fort George made them vulnerable to ambushes. As a result, on December 10, 1813, the Americans decided to abandon Fort George and Niagara, burning the town in their departure. Those who lived there only had an hour’s warning before they lost their homes. Mary’s house was spared though. How did she get so lucky again? The lighthouse was considered useful by the Americans for shipping and so they chose not to destroy it or the keeper’s house. As she did before, Mary came to the aid of those who needed her. She and her husband opened their doors to the newly homeless. Mary again provided hot food and medical care, which was undoubtedly much appreciated considering winter had already taken hold of the region.

Following the war, Mary’s acts were recognized by the Loyal and Patriotic Society of Upper Canada. They referred to her as “a heroine not to be frightened” and she was granted a gift twenty-five pounds sterling. When adjusted for inflation, her gift would be worth over £1,000 today.

      I know, it’s unfortunate. It would be nice to know what happened to the Henrys after the war.

      Ha! Wouldn’t that be something?
