Again though if you're desperate you don't need send part of your forces more than 2000 miles away. That would increase your desperation not relieve it. If Lyons and his men were dissenters who were causing problems that would be a reasonable explanation but the faction profile doesn't say this and indicates otherwise (Lyons gets promotions and is highly regarded by the Lost Hills leadership initially) and the Outcasts prove his expedition was not full of dissenters. It contained more than a few people loyal enough to Lost Hills to betray their Elder.
