 The main command was switched from the Fifth Army (General Hubert Gough) to the Second Army (General Herbert Plumer) on the southern flank.Rather than continue with optimistic, semi-open warfare tactics, Plumer planned a series of limited attacks, taking advantage of recent experience.Less ambitious infantry advances at the Battle of Menin Road, Battle of Polygon Wood, Battle of Broodseinde and Battle of Gravenstafel Ridge produced a advance in two weeks.
