The farcical irony of 9 Thermidor rears its ugly head again:
"[Robespierre] long defended Hébert. He angrily assailed Billaud when he first started to attack Danton."
From The Fall of Robespierre: 24 Hours in Revolutionary France, by Colin Jones, 2021, Chapter: 12.00/Midday, p. 196
No citation, but Choosing Terror by Marisa Linton, 2013, Chapter 10, gives the same account of Billaud's speech:
"[Billaud-Varenne] then accused Robespierre and his friends of having refused to abandon Hébert for as long as possible, and Robespierre in particular of having tried to protect Danton"
And her footnote cites Le Moniteur, 21:332, which I think refers to this in entry in the bibliography: [Moniteur (Le)], Réimpression de lʼancien Moniteur, 31 vols (Paris, Plon Frères, 1847). (So 21:332 = volume 21, page 332?)
...And, yes there it is on p. 332 of this edition on Google Books (it's p. 342 in the pdf), in Billaud's own words:
"And those who abandoned Hébert only when it was no longer possible for them to support him will be considered virtuous men! The first time I denounced Danton to the Committee, Robespierre rose like a madman, saying that he saw through my intentions, that I wanted to destroy the best patriots. All this made me see the abyss that has been dug beneath our feet. One must not hesitate either to fill it with our corpses or to triumph over the traitors."
And yet Robespierre is the blood-drinker, the terrorist, the tyrant who sent anyone who disagreed with him to the guillotine...
Whoever shouted The blood of Danton chokes him! should've better aimed their rage.
