Birdwood was warned by his medical staff that, quite apart from any feelings of humanity, the dead should be buried as quickly as possible to prevent infection spreading through the Army. When the afternoon had passed without any sign of the Turks renewing the attack, he sent off Aubrey Herbert to ask Hamilton aboard the Arcadian if he might arrange an armistice.

Herbert was an odd figure on the Anzac bridgehead — indeed, he would have been odd in any army on any battlefield: a Member of Parliament turned soldier, an eccentric, a poet and a scholar who, far from hating the Turks, was captivated by them. This did not mean he was disloyal — he was determined that they should be defeated — but he knew Turkey and Turkish very well, and he believed that with better handling by the politicians they might have been converted into allies. Of all the band who had been with Rupert Brooke at Alexandria he was the one most possessed of ideas, and despite his short-sightedness, his impulsive and agitated manner, he was very brave and saw very clearly under the façade of things. Hamilton was glad enough to have him on his staff as an intelligence officer with the rank of lieutenant-colonel, but he noted in his diary that he was ‘excessively unorthodox’.

Herbert chose to do his intelligence work in the front line at Anzac, and he proceeded to war in the manner of a nineteenth-century gentleman-adventurer. Servants were engaged at Lemnos, suitable horses and mules acquired, an adequate kit assembled, and off he went with an extraordinary assemblage of Greek and Levantine interpreters to the peninsula. There were staff troubles almost at once. A spy mania was raging through the Anzac bridgehead — the fear of spies seems to be endemic in every crisis in every military campaign — and his interpreters were arrested as many as four and five times a day. A terrible hail of shrapnel once fell on Herbert’s dugout, and the cook, a Greek named Christopher of the Black Lamp, with the tears pouring down his face gave two hours’ notice, though why it should be two hours and not two minutes he was unable to explain. Among these and other domestic anxieties Herbert continued with his work of questioning the Turkish prisoners and of acting as a kind of general confidant of the commanders in all questions relating to the habits and character of the enemy.

His methods of propaganda were very direct. He crawled into the foremost trenches and from there he addressed the enemy soldiers in their own language, urging them to desert, promising them good treatment and pointing out that the real quarrel of the Allies was not with Turkey but with the Germans. At times he actually got into trenches which communicated directly into the enemy emplacements, and lying on the dead bodies there, he called to the Turks through a single barrier of sandbags. Occasionally they would listen and enter into argument with him. More often they replied with hand-grenades — a thing which did not make Herbert very welcome with the Anzac troops — and in Constantinople one of the newspapers announced that there was someone in the Anzac bridgehead who was making a low attempt to lure the Turks from their duty by imitating the prayers of the muezzin.

It now fell to Herbert to put the case to Hamilton for an armistice. He argued that unless something was done quickly the situation would become intolerable: our own wounded as well as Turkish were still lying in the open, and in the hot sun the dead bodies were decomposing rapidly. Hamilton answered that he would not initiate any proposal himself, because the enemy would make propaganda of it, but if the Turks liked to come forward he was willing to grant them a cessation of hostilities for a limited period. It was agreed finally that notes could be thrown into the Turkish trenches telling them of this.

Meanwhile all May 20 had gone by and unknown to Hamilton and Herbert the soldiers at the front had already taken matters into their own hands. Towards evening an Australian colonel caused a Red Cross flag to be hoisted on a plateau at the lower end of the line. He intended to send out his stretcher-bearers to bring in a number of wounded Turks who were crying out pitiably in front of his trenches. Before they could move, however, the Turks put two bullets through the staff of the flag and brought it down. A moment later a man jumped up from the Turkish trenches and came running across no-man’s-land. He stopped on the parapet above the Australians’ heads, spoke a few words of apology, and then ran back to his own lines again. Immediately afterwards Red Crescent flags appeared above the enemy trenches, and Turkish stretcher-bearers came out. All firing ceased along the line, and in this eerie stillness General Walker, the commander of the 1st Australian Division, got up and walked towards the enemy. A group of Turkish officers came out to meet him, and for a while they stood there in the open, smoking, and talking in French. It was agreed that they should exchange letters on the subject of an armistice at 8 p.m. that night.

While this was going on another impromptu parley with the enemy had opened on another section of the line. It was now growing late and Birdwood, as soon as he heard what was happening, issued an order that no further burials were to be made that night. A note signed by the General’s A.D.C. was handed to a Turkish officer: ‘If you want a truce to bury your dead,’ it said, ‘send a staff officer, under a flag of truce, to our headquarters via the Gaba Tepe road, between 10 a.m. and 12 noon tomorrow.’

At this stage neither side seems to have been absolutely sure of themselves; there was a tense feeling that some act of treachery might occur at any moment, that an attack might be launched under the cover of the white flags — and indeed, an Australian soldier who had been out in no-man’s-land came back with the report that the enemy trenches were filled with men who were apparently ready to attack. Upon this the Australians opened fire on a party of stretcher-bearers who were still wandering about in the failing light. At once the Turkish artillery started up again and the bombardment continued intermittently all night.

Hamilton says he was very much annoyed when he heard of these irregular dealings with the enemy, and he dispatched Braithwaite to Anzac to handle the negotiations. The following letter, addressed to ‘Commandant en chef des Forces Britanniques, Sir John Hamilton,’ arrived from Liman von Sanders.

There is an air of fantasy about the conference that took place at Birdwood’s headquarters on May 22. Herbert walked through heavy showers of rain along the Gaba Tepe beach, and a ‘fierce Arab officer and a wandery-looking Turkish lieutenant’ came out to meet him. They sat down and smoked in a field of scarlet poppies. Presently Kemal himself arrived on horseback with other Turkish officers, and they were blindfolded and led on foot into the Anzac bridgehead. The British intelligence officers were anxious to give the impression that a great deal of barbed-wire entanglement had been erected on the beach, and they forced Kemal to keep goose-stepping over imaginary obstacles as he went along. Presently the Turks were remounted and taken to Birdwood’s dugout by the beach.
