query: What was the reason for the Mormons' decision to surrender in November 1838 during the Mormon War?
answer: The Mormons surrendered in November 1838 due to General John B. Clark's threat of violence, backed by Governor Boggs' Extermination Order (Executive Order 44), and considering the recent violence inflicted by the state militia.  They feared further violence and expulsion, choosing surrender to avoid more bloodshed.
