Yes, the Swiss guards were at the Tuileries guarding the royal suite when they were all killed then beheaded.
Their heads were propped on spears as the Royal family was escorted into Paris, and the last remaining guards were the first to be guillotined.
The Louis XXVI had Austrian troops sent in to stop the revolution and republicans, and when they were imprisoned, Marie Antoinette was giving away French troop movements to her family in Austria. That didn’t help his cause at all.
Oh, I hadn’t known that. But thank you for this fascinating bit of information.
And about unhappy, naive Marie Antoinette: that was maybe a factor in her process before the revolutionary tribunal.
I think, not just this, but especially her extravagant way of life had made her many enemies in France, so much indeed that it was difficult, even for many historians, to show her the sympathy which her cruel fate deserved - on a human level (imho).
