I was going back to finetooth my memory of Marius and Sulla, starting with the accounts of Cassius Dio, when I found this in book 30:

Cato, the greater part of whose army was from the city and rather too old for service, had little authority at best; and once, when he ventured to rebuke them because they were unwilling to work hard or obey orders readily, he came near being buried under the shower of missiles which they hurled at him. And he would certainly have been killed, if they had had plenty of stones; but since the site where they were assembled was under cultivation and happened to be very wet, he received no hurt from the clods of earth. - translation by Bill Thayer

Sound like someone we know? *G*
