Tempier described an incident of this to Eugene. The flag above the bishop’s house was of the Bourbon monarchy, and not the three-colored one of the revolution, and so he wrote:
The fray has started. The lieutenant-general, the commander of the national guard, the mayor and an aide-de-camp came to urgently request our prelate to fly the tricolor flag. His Excellency had a good answer for all their arguments. When the lieutenant-general started push matters a little too far, the prelate informed him that, as far as he was concerned, he would never order the flag to be flown, but that he was physically unable to repel those who might violate his dwelling.
Whereupon, the aide-de-camp went to the city hall to get the flag which they had been keeping in readiness, and returned with it, to put it in place. Since the old flag pole was broken, the aide had to tie the flag to a stick with a piece of string and go in search of a ladder at the cathedral; then, with the help of a few of the national guard, he put it up. Night came on while all this was taking place and a large crowd had gathered in front of the palace. However, everyone realizes very clearly that the flag was put there by force and violence.

To which, Eugene responded
According to the last thing you relate to me as having happened before the episcopal place, I would no longer stay in my palace; I would be out of there the following day. In no other place have they committed such violence… Once again, I do not think my uncle ought to stay in a house where they have proved to him that he is not the master.

Two days later:
I have intimated to you in several letters, my very dear friend, that my opinion would be that his Lordship depart for Italy in order not to be exposed to all the troubles that, at his very advanced age, could affect his morale to the point where his health would suffer considerably. I persist in having this opinion. Nice not being far he can very easily make the journey and its closeness would provide him the opportunity of not being a stranger to his diocese as long as the troubles last, and to return promptly as soon as his presence would be judged necessary… Since they have treated him in such an arrogant fashion in this instance, it is not difficult to foresee that they will not be more accommodating to him on further occasions. At his age, such shocks will not be felt with impunity; it is then only his natural right to avoid them by withdrawing for a time.
Remember that if he does not follow this advice, he will regret it. Sensible as he is, there is no other decision he could take, which will not disquiet him, perturb his mind more or less and have an adverse effect on his temperament.
