Tee hee...bested? In the words of John Paul Jones....I have not yet begun to fight......
Hmm..this is getting really interesting! Valid points there Aegon, some I agree with, some I don't. Still, I'm flattered people actually read the whole post, it was a bit longer than I originally planned! I shall respond to your points without trying to mix the issues of fathers and battles too much.
Something to consider - yes, Randyll needed atleast one military minded son to inherit house of Tarly, but did Samwell need to be turfed for that to happen? His younger bro showed considerable aptitude for the warrior life, perhaps Sam could have been trained to the diplomatic life instead?. I will concede that tradition stated that the family sword went to the eldest, but I'm sure there are examples in history where there were multiple sons, and each worked according to their talents. Before anyone tells me that is far too cuddly and reasonable for the times, remember that Willard Tyrell, the heir to the Tyrell empire, is crippled. He can't lead men into battle, or distinguish himself in the lists. in fact is described as gentle and intelligent, with little interest in war. The Tyrells seem to have found a place for him, nonetheless, and as they are a canny lot, it's unlikely to be a ceremonial place only.
Tyrion as well - OK, Aegon, there the thinking of the times rears its head again, in that Tyrion has been effectively denied his birthright, Casterly Rock, but his work was, IMO, the deciding factor in repelling Stannis' attack. However, his father continually reminded Tyrion of how little he was worth (in his opinion), leading to Tyrion (after much provocation) committing patricide.
To my mind, GRRM has set up two parallel figures - one the one side, we have the parenting displayed by Ned Stark and the Tyrells and on the other we have the Lannisters and Tarlys. I've noticed he has used this fascinating method before - so we have Cersei vs Sansa, for instance (love to see them face off in a catfight!). Can't think of any more right now, too tired.
TK - you may find works by Robert Bly to be of interest, specially 'Iron John'. He talks a lot about the relationship of boy children to their fathers and other male figures.
Your time in the military sounds interesting, Aegon. How realistically do you think GRRM has depicted the battle, from your experience?
