Big Annie's Reckoning — Uncover the Italian Hall Conspiracy

🎭Your Mission

You are an investigative reporter for a national newspaper, arriving in Calumet, USA, in the immediate aftermath of Christmas Eve, 1913.

While 400 striking miners

The Whistle of Uprising: 1913 in Calumet

« Nous sommes déterminés à ne pas céder un seul pouce tant que nos exigences ne seront pas satisfaites. Nous lutterons jusqu'au bout. »
Charles Moyer, Président de la Western Federation of Miners, 1913

Michigan's Copper Battle

The Keweenaw Peninsula in northern Michigan was, in the 19th and early 20th centuries, the scene of intense copper mining, making Michigan one of the world's leading producers. The Calumet & Hecla Mining Company (C&H), founded in 1871, dominated the region's economy, employing thousands of miners, predominantly European immigrants. Working conditions were harsh: low wages, long hours, high risks, and the absence of any effective union representation. The introduction of the 'one-man drill' in 1913, intended to increase productivity, was the last straw, threatening to drastically reduce wages and jobs.

On July 23, 1913, the Western Federation of Miners (WFM) launched a massive strike, demanding better wages, an eight-hour workday, and union recognition. C&H refused all negotiation, hiring strikebreakers and calling in the National Guard. The conflict lasted over nine months, marked by violence, evictions from company housing, and intense community polarization. The tragic climax was the Italian Hall fire on Christmas Eve 1913, where 73 people, including 59 children of strikers, perished in a deadly stampede, an event whose responsibilities remain controversial and left a deep scar on American labor history.
