This was a more serious matter, for the Senussi were the largest native tribe in Egypt, and Turkish and German officers had been very busy amongst them. Some account of the operations against them has already been published, but I believe it concerns mainly the Duke of Westminster's spirited dash with his armoured cars to rescue the shipwrecked survivors of the _Tara_, who were grossly ill-treated by the Senussi. Yet right up to the end of 1917 they were a source of trouble, and in 1915 the situation became so serious that a strong punitive force had to be sent to Mersa Matruh, on the Western Frontier of Egypt, to cope with it. Here, I think, is where we must make our bow, for we had some small place in these operations; it was, in fact, our introduction to actual fighting, though we had already spent many torrid weeks on the Suez Canal. And no better _mise en scene_ could we have than the old _Missa_, for the story of the campaign would be incomplete without mention of her; she was unique. Besides, everybody in Egypt knows the _Missa_. Those who had the misfortune to know her intimately speak of her with revilings and cast slurs upon her parentage. Far back down the ages, possibly about the time when the admirable Mr. Stephenson was busy practising with his locomotive, the _Missa_ might have been a respectable ship, but her engines had been replaced so many times by others more pernicious and evil-smelling, and new boards had been nailed so frequently and promiscuously about the hull, that she resembled nothing so much as an aged female of indifferent repute decked in juvenile and unseemly clothes; and her conduct matched her looks. Most men in the army will have noticed that the authorities nearly always order a move or begin a "show" on the day of rest. I am no statistician, but if the tally of these lost hours in bed of a Sunday morning were kept, the army would have a few weeks' arrears of sleep to make up. On this particular occasion we went one better than Sunday; we began on a day when normally peace and goodwill go ringing round the world: Christmas Day, 1915. If there was any peace and goodwill about we failed to notice it, for it was blowing and raining hard, and we had to get half a battery of horse-artillery on board that deplorable ship. It is no joke at the best of times embarking horses and mules; and as, in addition to the weather, we had the _Missa_ to deal with, the humour of the proceedings did not strike any one--except the onlookers. For she rolled and pitched and plunged and dived as she lay there at her moorings. She was never still a moment, and, in a word, behaved like the graceless, mercurial baggage she was. But she was beaten in the end.
