1 on 1 duels are glamorous but are more apt for literary works than warfare which is really a branch of political/economic science.
Modern samurai popularity seems to owe a lot to Kurosawa's desire to film Westerns...I can't recall exactly, but I had come across a few accounts where public resentment of the samurai class as corrupt government officials surged from time to time...
I thought that until the last few centuries foraging/pillaging was the main way armies were fed in the field. Gives the obvious advantage of not needing to maintain and defend supply lines.
Feudal social structures are just very counterintuitive to us. We think of is as being a job but it was a lot more built on personal relationships than that, and a Samurai's relationships with his inferiors depended largely on effectively scaring away unpopular criminals. That's why I say it's a role more like a police officer's than a soldier's, but it was really quite unlike either.
Assuming a rhetorical question, can you share sources?
