Greetings fellow Civs! First post here even though I have over 130 hours of Civ IV gameplay registered on my steam account. Very addictive game, so complex with so many ways to play, the funniest being merciless back-stabbing wars. 
I have two specific questions, I'm trying to understand the mechanics of terrain defense bonuses when attacking:
1. Imagine a scenario where I'm doing an early attack to a city protected by 3 fortified archers on a flat terrain, surrounded by forest tiles. I have a stack of 6 swordmen, 3 with city raider promotion and 3 with forest defense promotion. I move them all to a forest tile right next to the city, ready for the attack. When I attack, my swordmen move to the city tile to fight. At this point do I benefit from the forest tile defense bonus or is there no bonus at all because the fight happens on the city tile? Is the forest defense promotion worthless in that case?
2. Imagine the same scenario as above except that before attacking I fortify my swordmen until the full defensive bonus is reached. When I move to attack, does the fortified bonus still applies or is it lost as soon as I move?
Thanks in advance!
