Such thoughts often passed through his mind at night for, during the day, he had not a minute to himself. He was almost sure, now, that the men had discovered his identity, by the many little marks of kindness they had shown him, and by the manner in which his fellow sub-officers always spoke to him with a certain air of respect. This, however, did not worry him. He felt certain that they would keep the secret; and at the end of the campaign he must, of course, disclose himself and obtain his discharge. Until then, no one would have time to think much of the matter, still less find any opportunity of reporting it to Colonel Kelly.
He wondered how the colonel would take it, when he went up to say who he was. He did not think he would be very seriously angry, though probably he would wig him sharply. At any rate he had not done badly, and had brought no discredit to the regiment.
He had unconsciously adopted the regimental belief that he was a lucky man, and should get through the campaign unhurt. He was particularly anxious that he should do so as, were he confined in hospital for a few days, he would have no opportunity of renewing his stain; in which case he would undoubtedly be detected. They had advanced so far now, however, that even if he were discovered, they could hardly send him back before he got to Chitral. He might, of course, be detained at Reshun, which would be a horrible nuisance.
One night his camp mate said to him:
"You ought to be with the officers, Bullen sahib. It is not right for you to be working as we do."
"Why do you call me Bullen Sahib, Pertusal?"
"Everyone knows it, sahib. Little by little we nave found you out. We had some suspicions from the first, but now we are sure of it. Only your father's son would have fought as you did on the hill and, when we came to look very closely at you, we all recognized you, in spite of your dye."
"Then I wish I hadn't fought quite so hard, Pertusal, for I had hoped that I had altogether escaped recognition. I thought that I could have gone through the campaign without anyone suspecting who I was."
"We did not suspect at first, sahib. We quite took you for one of ourselves. No, the cheerfulness with which you bore your hardships, and your readiness to assist anyone, surprised us. You were so different from us all that we could not help wondering who you were; but I don't think any of us really suspected that you were Captain Bullen's son, till that fight. I know that when I was busy fighting, sorely pushed as we were, I wondered when I heard you shout in English; and I had heard you call out so often, when you were playing cricket with the officers, that I recognized your voice at once.
"Then the wonder that we felt about you ceased. It seemed for a moment impossible, for I had seen you go off with the sick convoy. Then it seemed to me that it was just the thing that Captain Bullen's son might be expected to do. You would naturally want to see fighting, but I did wonder how you managed to come back and get enlisted into the regiment. I remember, now, that I wondered a little the first night you joined. You were in uniform and, as a rule, recruits don't go into uniform for some time after they have joined. It was therefore remarkable that you should turn up in uniform, rifle and all."
