BEIRUT, Lebanon — When pro-government forces retook her hometown from Syrian rebels, Nisrine accepted the same surrender deal the government has offered tens of thousands of Syrians: a one-way bus trip to a place she had never been — the northern, rebel-held province of Idlib.

Since Syria’s war began, the population of Idlib has doubled as it has taken in a motley mix of fleeing civilians, defeated rebels, hard-line jihadists and those like Nisrine who have packed up their families to ride the government surrender bus.

But as government forces wrap up a blistering campaign in eastern Ghouta, Idlib is likely to be the next target. And this time, there will be nowhere else to run.

“Maybe this is the last chapter of the revolution,” Nisrine, 36, an Arabic teacher from the onetime tourist resort of Madaya, said in an online interview recently. “Syrians are killing Syrians. Nothing matters anymore. We decided to die standing up. I’m sad for the revolution, how it’s gone, how people called for freedom and now it’s gone.”
