That’s exactly what I said. The national guard did not force anyone to work as the person I responded to implied (edit: I think I misread their comment in part, so that’s part of the confusion). In any case, to they were deployed to allow strike breakers to get to work, and to reduce violence. Ultimately, they screwed up when their forces were cut and became the violence they were deployed to prevent; these old strikes were not the “peaceful protest” strikes we see today, they could get quite violent.
