Wartime Wedding

War is a brutal, tragic thing. Expect plenty of Cruel And Unusual Deaths and Tear Jerkers. The atmosphere of a lot of war stories is generally saddening and depressing, if not outright horrifying and peppered with Nightmare Fuel. That said, when a writer thinks that enough is enough and that these poor characters need a bit of happiness in their lives without deviating from the somber war genre, then what better way to show that than have two characters get married?

The Wartime Wedding is a great way to put a Hope Spot in the middle of a story in order to lighten the mood, considering that among other things, a marriage symbolizes love and unity, reminding the characters in the universe that things such as happiness still exist.

This can come in three types (but is not limited to them):

Weddings right prior to war breaking out or right in the beginning of it: These marriages are usually rushed and can represent calm before the storm. It can be particularly ominous Foreshadowing. Often ends in the fresh husband going off to war. These bridegrooms seem to have a fairly low chance of survival.
Weddings during war: Most commonly used as a Hope Spot, especially when characters are "tired of all the fighting." This can also be done before the Final Battle, as one last "I love you," and to ensure that the now-wife will be compensated if the hero dies in battle. In this case, his odds of survival are about 50/50.
Weddings right after war: When the wartime sweethearts have Hooked Up Afterwards, they're very likely to get married to show that, somehow, the characters are moving on with their lives. This type of wartime wedding generally symbolizes the beginning of recovery. Oftentimes used as a Bittersweet Ending.

The Star-Crossed Lovers are subject to this a lot of the time in war stories. Expect the couple to Altar the Speed. Compare Married At Sea. Beware the possibly unmarked spoilers!
