@ManOnTheMoon34:

Would it have killed you to make a few
interesting posts over the next few days?
To the guy who was talking about losing like crazy: Unless you made a custom game with "Reload Random Seed" enabled, it won't matter what you do. You will lose the next fight. To reset the RNG, I believe you have to wait for the next turn and try again.
Strictly speaking, you get the same next number from the RNG in the replayed fight. If you replay the same attack, you lose again. If you pick a different unit to attack with, if it gets the same attack odds you also lose again. If you pick a different unit with BETTER odds, it is faintly possibly that you might win if the random number was only barely big enough to lose you the first fight.
The way to "game" this is to force that "bad" random number to be used for something else. For example, reload and fight a battle that you don't care about first, such as having a wimpy obsolete unit take the fall. More subtly, you could back up to the start of your previous turn and automate your workers; that gets the game to call the RNG several times to figure out what the workers will do, when it wouldn't have done so with un-automated workers (not 100% sure -- never tried it, but read someone's claim that it worked).
ISTM it's not usually* worth the trouble. Depending on your personal capacity for taking "acceptable losses" (mine being far too low, I think):
- Suck it up and take the hit. Make sure you have extra units to allow for expected losses; for axe rushing archers not on hills, I've heard people suggest a 2:1 ratio. Even so, random rolls are random rolls, and a long sequence of bad rolls is bound to come up eventually. We notice those; we don't notice the much longer sequences of ordinary rolls.
- Set "new random seed on reload" as AJ11 suggested.
- Use the worldbuilder to delete enemy units or create more of your own.
- Play a game where you can pick scenarios without combat, like Pharaoh. This seems to be my personal favourite sometimes.
To enjoy Civ as-is, #1 is the way to go.
(there ought to be a bunch of smileys mixed in with most of those suggestions. here's a few to randomly redistribute:

*I have been known to use "new seed on reload" to avoid bad random events, like Vedic Aryans or Bermuda Triangle, but I'd be better off learning how to edit the config file to eliminate them. I know it's not that hard, but I'm lazy (plus irrationally nervous about possibly breaking something).
