"Isis had not yet formed, but the men I could see inside that building, darting between the windows and the stairwells, would join the group when it raised its colours several months later." [From The Guardian.]
Is the clause the men (...) would join the group when it raised its colours several months later expressed in the future in-the-past tense in the above context?
I'm not a teacher and I'm not a native speaker of English.
It's future in the past, but I would not call it a tense. It's a modal form to me.
