Your troops will return to the Catacombs without attacking the hostile Castle or Hamlet in the following cases:
1. Your opponent has activated Weor's Protection over their Castle.
2. Your opponent has relocated their Castle to another place on the global map.
3. The targeted Hamlet had depleted before your battle squad arrived to capture it.
4. Your opponent lost control over the Hamlet.
Please note that it is impossible to attack a Hamlet which isn't controlled by any player.
Many players use a special tactic to minimize their losses: when the player who keeps Hamlet notices that it was attacked several times, they recall their reinforcements, leaving it unclaimed.
