Western Army

The Western Army refers to the alliance who sought to defend the Toyotomi reign after Hideyoshi's death. Officers under this faction are Mitsunari Ishida's friends or Toyotomi loyalists. Two main divisions are the Sanada loyalists and the Uesugi troops. These generals either participated in the decisive battle at Sekigahara or were sent to defend Ueda Castle or Hasedo.
