To Englishmen, therefore, whose experience of this situation is long, varied, and actual, Mr. Baddeley's book on the Russians in the Caucasus should be of exceptional interest. It is indeed well worth studying by those upon whom, whether at home or in India, has been imposed the arduous duty of superintending our policy in dealing with the Afghan tribes for the protection of our Indian districts. It is true that the conditions and circumstances, military and political, under which Russia prosecuted her long war with the Caucasian mountaineers, rendered her position in many respects different from that in which the English found themselves when they first came into contact with Afghanistan, and which has changed very little in the course of sixty years. The aims and purposes of the two governments were by no means the same. Yet in both cases we have a story of the obstinate resistance opposed by fierce and free clans to the arms of a powerful empire, of perilous campaigns amid rugged hills and passes, of the hazards and misfortunes to which disciplined troops are always liable when they encounter resolute and fanatical defenders of a difficult country. Mr. Baddeley's book contains an authentic narrative, founded on diligent study of official documents and on the accounts of those who took part in the fighting, of the operations by which the Mohammedan tribes of the Caucasus were finally subdued, after fierce and protracted resistance, by Russian armies, and their country was annexed to the dominions of the Czar. His knowledge of this region is evidently derived from personal exploration; and in the Introduction to his book he has spared no pains to explain to his readers its geographical position, its topography, its physical features, and the extraordinary diversity of races and languages which it contained. We learn that the chain of mountains which was originally known by the name of the Caucasus stretches, with a total length of 650 miles, from the Caspian to the Black Sea. Toward the north is a tract of dense forest, intersected by numerous streams flowing down from the mountains; and beyond lies the high plateau of Daghestan, 'through which the rivers have cut their way to a depth often of thousands of feet, the whole backed and ribbed, south and west, by mountain ranges having many peaks often over 13,000 feet in height.' In the forest tract, to which the Russians gave the name of Tchetchnia, their armies were constantly entangled; and their difficulties in reducing the inhabitants to subjection were quite as great as in conquering the highland tribes of Daghestan. Throughout the eighteenth century, and even earlier, the Russians had been pushing southward toward the Black Sea and the Caspian, and had gradually taken under their authority and protection the Cossack tribes who were settled on the steppes that spread along the northern border of the Caucasus. On this border they
