Thanks very much, I'm so glad you like the characterisation. Thanks also for pointing out those little errors!
They were indeed attacked immediately... at least, if you believe what Caesar says in his commentaries (which have to be taken with a healthy pinch of salt!). Caesar tells the story about the 10th's standard-bearer leaping in first, which is what made me decide to make him one of Marcus's friends.
I will now give the manuscript a good pruning 😁 Thanks again for your time!
