Nivelle", although the subordination of Haig to Nivelle had not been specifically discussed. At Calais (26–7 February), after the railway experts had been sent away, at Lloyd George's request Nivelle produced rules governing the relations between the British and French armies, to be binding also on their successors. Nivelle was to exercise, through British staff at GQG, operational command (including control of logistics and food) of British forces, with Haig left in control only of discipline (which could not legally be placed in foreign hands) and forbidden to make direct contact with London. Haig, Spears later wrote, "had become a cipher, and (his) units were to be dispersed at the will of the French command, like the Senegalese Regiments, like the Moroccans, like the Foreign Legion, until (his) massed thousands had become mere khaki pawns scattered among the sky-blue pawns" The plans were brought to Robertson, who feeling unwell had dined with Maurice in his room, at around 9pm. In Spears' famous account Robertson's face "went the colour of mahogany … his eyebrows slanted outwards like a forest of bayonets held at the charge – in fact he showed every sign of having a fit" He shouted "Get 'Aig!". Haig and Robertson visited Lloyd George – one of Robertson's objections was that the agreement could not be binding on Dominion troops – who told them that he had the authority of the War Cabinet and that, although Nivelle's demands were "excessive", they must have a scheme agreed by 8am. The next morning, after Nivelle had claimed he had not personally drawn up the scheme and professed astonishment that the British generals had not already been told of it, Robertson "ramped up and down the room, talking about the horrible idea of putting "the wonderful army" under a Frenchman, swearing he would never serve under one, nor his son either, and that no-one could order him to". Hankey drew up a compromise rather than see Haig and Robertson resign, with Haig still under Nivelle's orders but with tactical control of British forces and right of appeal to the War Cabinet. Robertson later (3 March) regretted even agreeing to this. Eroding the agreement Robertson wrote to Haig (28 February) that Lloyd George was "an awful liar" for claiming that the French had originated the proposal (the Prime Minister had in fact met Major Berthier de Sauvigny (15 February), a French liaison officer
