The first glance showed me that I had lit on a treasure. It was the staff map of the Erzerum defences, showing the forts and the field trenches, with little notes scribbled in Stumm's neat small handwriting. I got out the big map which I had taken from Blenkiron, and made out the general lie of the land. I saw the horseshoe of Deve Boyun to the east which the Russian guns were battering. Stumm's was just like the kind of squared artillery map we used in France, 1 in 10,000, with spidery red lines showing the trenches, but with the difference that it was the Turkish trenches that were shown in detail and the Russian only roughly indicated. The thing was really a confidential plan of the whole Erzerum enceinte, and would be worth untold gold to the enemy. No wonder Stumm had been in a wax at its loss.
The Deve Boyun lines seemed to me monstrously strong, and I remembered the merits of the Turk as a fighter behind strong defences. It looked as if Russia were up against a second Plevna or a new Gallipoli.
Then I took to studying the flanks. South lay the Palantuken range of mountains, with forts defending the passes, where ran the roads to Mush and Lake Van. That side, too, looked pretty strong. North in the valley of the Euphrates I made out two big forts, Tafta and Kara Gubek, defending the road from Olti. On this part of the map Stumm's notes were plentiful, and I gave them all my attention. I remembered Blenkiron's news about the Russians advancing on a broad front, for it was clear that Stumm was taking pains about the flank of the fortress.
Kara Gubek was the point of interest. It stood on a rib of land between two peaks, which from the contour lines rose very steep. So long as it was held it was clear that no invader could move down the Euphrates glen. Stumm had appended a note to the peaks - 'not fortified'; and about two miles to the north-east there was a red cross and the name 'Prjevalsky'. I assumed that to be the farthest point yet reached by the right wing of the Russian attack.
Then I turned to the paper from which Stumm had copied the jottings on to his map. It was typewritten, and consisted of notes on different points. One was headed 'Kara Gubek' and read: 'No time to fortify adjacent peaks. Difficult for enemy to get batteries there, but not impossible. This the real point of danger, for if Prjevalsky wins the Peaks Kara Gubek and Tafta must fall, and enemy will be on left rear of Deve Boyun main position.'
I was soldier enough to see the tremendous importance of this note. On Kara Gubek depended the defence of Erzerum, and it was a broken reed if one knew where the weakness lay. Yet, searching the map again, I could not believe that any mortal commander would see any chance in the adjacent peaks, even if he thought them unfortified. That was information confined to the Turkish and German staff. But if it could be conveyed to the Grand Duke he would have Erzerum in his power in a day. Otherwise he would go on battering at the Deve Boyun ridge for weeks, and long ere he won it the Gallipoli divisions would arrive, he would be out- numbered by two to one, and his chance would have vanished.
My discovery set me pacing up and down that cellar in a perfect fever of excitement. I longed for wireless, a carrier pigeon, an aeroplane - anything to bridge over that space of half a dozen miles between me and the Russian lines. It was maddening to have stumbled on vital news and to be wholly unable to use it. How could three fugitives in a cellar, with the whole hornet's nest of Turkey and Germany stirred up against them, hope to send this message of life and death?
I went back to the map and examined the nearest Russian positions. They were carefully marked. Prjevalsky in the north, the main force beyond Deve Boyun, and the southern columns up to the passes of the Palantuken but not yet across them. I could not know which was nearest to us till I discovered where we were. And as I thought of this I began to see the rudiments of a desperate plan. It depended on Peter, now slumbering like a tired dog on a couch of straw.
Hussin had locked the door and I must wait for information till he came back. But suddenly I noticed a trap in the roof, which had evidently been used for raising and lowering the cellar's stores. It looked ill-fitting and might be unbarred, so I pulled the table below it, and found that with a little effort I could raise the flap. I knew I was taking immense risks, but I was so keen on my plan that I disregarded them. After some trouble I got the thing prised open, and catching the edges of the hole with my fingers raised my body and got my knees on the edge.
It was the outbuilding of which our refuge was the cellar, and it was half filled with light. Not a soul was there, and I hunted about till I found what I wanted. This was a ladder leading to a sort of loft, which in turn gave access to the roof. Here I had to be very careful, for I might be overlooked from the high buildings. But by good luck there was a trellis for grape vines across the place, which gave a kind of shelter. Lying flat on my face I stared over a great expanse of country.
Looking north I saw the city in a haze of morning smoke, and, beyond, the plain of the Euphrates and the opening of the glen where the river left the hills. Up there, among the snowy heights, were Tafta and Kara Gubek. To the east was the ridge of Deve Boyun, where the mist was breaking before the winter's sun. On the roads up to it I saw transport moving, I saw the circle of the inner forts, but for a moment the guns were silent. South rose a great wall of white mountain, which I took to be the Palantuken. I could see the roads running to the passes, and the smoke of camps and horse-lines right under the cliffs.
I had learned what I needed. We were in the outbuildings of a big country house two or three miles south of the city. The nearest point of the Russian front was somewhere in the foothills of the Palantuken.
As I descended I heard, thin and faint and beautiful, like the cry of a wild bird, the muezzin from the minarets of Erzerum.
When I dropped through the trap the others were awake. Hussin was setting food on the table, and viewing my descent with anxious disapproval.
'It's all right,' I said; 'I won't do it again, for I've found out all I wanted. Peter, old man, the biggest job of your life is before you!'
Chapter 19 Greenmantle
Peter scarcely looked up from his breakfast.
'I'm willing, Dick,' he said. 'But you mustn't ask me to be friends with Stumm. He makes my stomach cold, that one.'
For the first time he had stopped calling me 'Cornelis'. The day of make-believe was over for all of us.
'Not to be friends with him,' I said, 'but to bust him and all his kind.'
'Then I'm ready,' said Peter cheerfully. 'What is it?'
I spread out the maps on the divan. There was no light in the place but Blenkiron's electric torch, for Hussin had put out the lantern. Peter got his nose into the things at once, for his intelligence work in the Boer War had made him handy with maps. It didn't want much telling from me to explain to him the importance of the one I had looted.
'That news is worth many a million pounds,' said he, wrinkling his brows, and scratching delicately the tip of his left ear. It was a way he had when he was startled.
'How can we get it to our friends?'
Peter cogitated. 'There is but one way. A man must take it. Once, I remember, when we fought the Matabele it was necessary to find out whether the chief Makapan was living. Some said he had died, others that he'd gone over the Portuguese border, but I believed he lived. No native could tell us, and since his kraal was well defended no runner could get through. So it was necessary to send a man.'
Peter lifted up his head and laughed. 'The man found the chief Makapan. He was very much alive, and made good shooting with a shot-gun. But the man brought the chief Makapan out of his kraal and handed him over to the Mounted Police. You remember Captain Arcoll, Dick - Jim Arcoll? Well, Jim laughed
