[@CirusArvennicus]We leave to battle in 13:30, I don't think we have time for a side quest to retrieve a lance.
Also chances are high that the Lance was already taken by the imperials as a valuable asset and sits in one of their warehouses nearby.
Attacking an imperial base with a single squad goes beyond suicidal.
You may wish to change this IMO.
Or wait for Lennon but I think the general response would be similar.
