"Favourite Doomed Army" Topic

I have a psychological quirk where I feel too much sympathy for losers. This translates to my hobby, where armies that were historically doomed, seem inordinately interesting.

I don't think I'm alone and many of us enjoy commanding armies that are historically outclassed, under-equipped or simply facing impossible odds.

Which "hopeless" or disadvantaged historical army do you most enjoy putting on the tabletop—and why?

Possibilities might include:

Late Romans
Napoleonic-era Neapolitans
Early-war French (1940)
Late-war Confederates
Anyone fighting the Imperial Romans
ECW Royalists
Definitely the Jacobites of the '45 and so on.

Is it the challenge, the unusual troop mix, the historical sympathy or simply the pleasure of trying to achieve the impossible?

French in 1870
Late Eastern Roman Empire

I gather this is not just a matter of my not going for the current "killer army" for some tournament or the other.

Kingdom of Greece 1897--I wanted some Greeks for the Colonial Era and knew I'd find much more information on an army that actually fought a war during the period, hence 1897. It wasn't until later that I slowly began to realize that I might well have modeled the least effective European army of the 1890s.

Sub-Roman British--Very romantic, with Celtic themes and King Arthur.

French 1940. Well, I thought they were underrated and could have done better.

Something I would like to have done is 1450s Byzantine. Yes, I think they could have done better, but they also have unusual troops, and I do have some historical sympathy for them. I'm not so sure about them now because it is getting late in my life to do another army and because in some ways, their situation reflects too much of the current political situation.
