In the Cranston Snord's Irregulars, a unit known to work for House Marik and called "23rd Herron Regiment" attacks Hyde, but it is beaten by the Cranston Snord's Irregulars and surrenders.
The unit is sent to have full support.
I've found no other information on this unit, and I'm not even sure it is a Marik Line unit or Mercenary. Also, its composition is unknown... they are classified as Regiment but... even with Cranston Snord's Irregulars being very good, they could never beat a unit that big.
