I've come upon something while writing just now I thought I'd ask for some advice on to get a feel for what others would/have done. One of my POV characters has returned to his base of operations (keep in mind this is a future history book set in the US), an island and is returning to his home to rest before going out again (he's a guerrilla leader) and in his thoughts he's thinking about his home, the island, etc. Now as I was writing this I thought if I was a reader I'd want some backstory how they captured it, somewhat to give a clue since it's in enemy territory. Problem is I don't want to infodump, I don't like it much as a reader and know its reputation as far as writing is concerned. Now what would you do? I wasn't planning on a big flashback at all, but maybe a paragraph that'd give a reader insight into how him and his team captured it.
