Did Arbuthnot belong to Fisher's faction or Beresford's?
Short answerHe was broadly on Fisher's side and Jellicoe supported his appointment, although he also had friends across the factional divide.
NotesArbuthnot's connections crossed the naval feud. Jellicoe supported him in obtaining his post, and he is associated more closely with Fisher's side. Friendships with the opposing group make a rigid factional label misleading.
