To be rather off-topic, there does not exist any canon which prohibits ordinations of multiple men at one time to a given order.
To be on-topic, Fr. John Anderson was mentioned. As I heard it, which is very sad, he saw the looming split between the parish and the hierarchy, and did everything he could to avoid getting caught in the middle. He begged prior to the impending clash to be released to go help his elderly mother, who really needed assistance, but this request was denied. He tried to avoid getting punished with the rest, but it was impossible and he was uncanonically punished with all the rest. Doubtless this anti-canonical injustice is what spurred him to take the even more uncanonical and indeed non-Christian action, of apostasising from the faith of Christ and the apostles.
I don't think either 'side' was "pure as the driven snow."
