As many as two hundred workers died, though remarkably no one bothered, then or afterward, to make a formal count. Hundreds more were injured. Many of those trapped inside were hideously incinerated as fires spread from broken lamps.
"Remarkably"? Not really. Like you said, they were female Irish immigrant factory workers. Of course the powers that be didn't do a formal count. (Also, "hideously incinerated"? Jesus, the word choice here...)
