The most notable deviation of the film from reality, and the one for which it has been most criticized, is its portrayal of the chain of command at the Nek. Although he is seen wearing an AIF uniform, Colonel Robinson is often mistaken for an Englishman due to his accent. In reality, Col. Robinson speaks with a clipped accent typical for an upper class Australian of the period. Colonel Robinson's character equates to the brigade-major of the 3rd Brigade, Colonel John Antill, an Australian Boer War veteran. Indeed, very little British command and control was exercised at the Nek. In his best-selling history, "Gallipoli" (2001), Les Carlyon agrees that the film unfairly portrays the English during the battle and Carlyon lays the blame squarely at the feet of Antill and 3rd Australian Light Horse Brigade commander Brigadier General Frederic Hughes: "The scale of the tragedy of the Nek was mostly the work of two Australian incompetents, Hughes and Antill." The film implies that the fictional and benevolent General Gardiner called off the attack, when in reality the attack petered out when half of the 4th wave charged without orders while the surviving regimental commander in the trenches, Lieutenant Colonel Noel Brazier, attempted to get the attack called off.
