Shadowgraves, about 2/3 the way through the third year. The caravan is currently here, most of the fort is hauling masterwork crafts to the depot, and we have 2 dwarves in the hospital.

The swordsdwarves only squad is not to be used in combat! They're raw recruits with none or almost no skill at all, except for the Skilled leader.
Any migrants with combat skills above competent should go in squad 1
Don't pull the lever which says RELEASE THE BEAR.
There is a well underneath the courtyard, attatched to a small cistern.
