Captain America #321 (1986)
By Mark Gruenwald, Paul Neary, John Beatty
Background: Trying to save a group of hostages, Captain America has had to kill one of the Ultimatum terrorists led by the Flag-Smasher.
So, What Happens? In the middle of a blizzard, Cap and SHIELD storm the Ultimatum base in the Swiss Alps, with the Avenger especially motivated to capture the Flag-Smasher after the recent events. Seeing his enemy about to leave on board of a helicopter, Cap jumps on it, and in the ensuing fight the out-of-control chopper smashes into the Alps and explodes. Both Cap and the Flag-Smasher are saved by the soft snow and resume their fight, but eventually the terrorist falls into a deep chasm. Unable to help due to the raging snowstorm, Cap is forced to dig a burrow for himself and wait until the weather improves. He's eventually able to get out and reach the bottom of the chasm, recovering the unconscious terrorist who appears to have a broken leg. Once again, Cap digs a shelter for the both of them, struggling to stay warm and keep his foe alive during the frosty alpine night. The next morning, Cap takes the now conscious Flag-Smasher and starts the long journey towards civilization, trying to explain his point of view and philosophies. He's interrupted by a Ultimatum helicopter, but it turns out to be a blessing in disguise as the hero quickly takes the terrorists down. The Flag-Smasher takes the chance to grab a gun and reiterate that his opinion of Captain America hasn't changed any despite their conversation or the fact that the hero has saved his life. However he eventually accepts he doesn't have a chance and gives up, promising to kill Cap another day. Focused on the principle that every life is precious, Cap flies the chopper back to base and delivers the Flag-Smasher to SHIELD.
