I watched the movie "21 Bridges" and, as someone who grew up in NYC, didn't believe there were 21 bridges in and out of Manhattan. I googled it and, who would have guessed, there are 21. However, some are for foot traffic only, some for trains only, and some that connect to islands, like Roosevelt Island.
So why am I bringing this up in this thread?
The following is from an article on the movie:
"We've got 21 bridges in and out of Manhattan," Detective Andre Davis (Chadwick Boseman) says in the film. "Shut 'em down. Three rivers, close 'em. Four tunnels, block 'em. Stop every train and loot the subways." Never mind the fact that this would be a massive undertaking to do in one night (and in a city that, frankly, DGAF about government-ordered traffic patterns), but the movie doesn't give mind to that small detail. In fact, the bridges actually aren't that big of a thing at all. The film's focus is on Andre chasing two drug traffickers.
So, although "the fact that this would be a massive undertaking to do in one night," "the movie doesn't give mind to that small detail." Why? Because "the bridges actually aren't that big of a thing at all" as it pertains to the movie. The movie isn't about shutting down the bridges. It's about the manhunt.
That relates to our discussion. Did the soldiers in my story hear the mortar coming? Had the battle already begun? I don't give mind to that small detail because it's not that big a thing in the story.
This, from the article, explains it better than I just did:
That's all fine, but we were promised bridges! Even though we may want information on the logistics of how the bridges were shut down, the movie doesn't really care. The point is, there are 21 bridges and they get shut down.
