Were Monash and Currie excluded because they were colonial officers?

Could Monash or Currie have replaced Haig, with colonial status the only reason they did not?

The reply rejects colonial status as a sufficient explanation and emphasizes Plumer's influence and reluctance to take Haig's political role.

A participant suggests that Monash or Currie could have done as well as Haig and were held back because they were colonial officers. The reply rejects that as the whole explanation. It describes efforts to promote alternatives and connects Monash's appeal with Plumer's influence. Plumer is portrayed as unwilling to oppose Haig and content to leave political management to him. The exchange answers an interpretation of promotion politics; it does not demonstrate which commander would have produced the best campaign.
