That the Russian armies were forced to halt on the edge of Afghanistan is thus a point of cardinal importance, and it marks a turning-point in the career of her expansion. It also produced a situation that is the outcome of the different strategy adopted by England and Russia respectively, in circumstances not otherwise very dissimilar. For whereas the Russians had been compelled by imperative political and military exigencies to conquer and occupy the Caucasian highlands, the policy of the British Government has always been not to subjugate Afghanistan, but to preserve its independence and to fortify it as an outwork for the protection of the gates of India. It is due to this fundamental distinction of aim and object that the history of the relations of the British with Afghanistan during the nineteenth century, and of their management of the tribes on the Afghan border, differs widely from Mr. Baddeley's narrative of events and transactions in the Caucasus. Nevertheless in both instances the general situation presented a strong resemblance. The Russians, pushing their dominion down from the north to the Black Sea and the Caspian, were checked and baffled for many years by the woods and precipices that lay across the line of their march into Trans-Caspia. The British, moving up by long strides north-westward across India, came to a halt at the foot of the Afghan hills fifty years ago; and to this day they have scarcely moved farther. Here they were met by races almost identical in character and circumstances with the tribes of Daghestan, fanatically attached to the faith of Islam, profoundly influenced by religious preachers, prizing their liberty above their lives, and looking down from their rugged uplands upon a great military power that had swept away many principalities and subdued all the cities of the plain below. If the British had pressed onward and endeavoured to take possession of Afghanistan [which had indeed been occupied by the Moghul empire in its prime] they would certainly have been involved in a series of sanguinary conflicts, revolts, and costly expeditions not unlike those which put so severe a strain upon the Russian armies in the Caucasus. This, as we know, they did not do; they adopted the alternative of asserting an exclusive protectorate over the country; they were content to remain outside it so long as no rival power was allowed to set foot in it. Yet we know that even this much more prudent policy was carried out at a heavy cost. The British army suffered at least one grave disaster by the total destruction of a division in the retreat from Kabul in the winter of 1842-3. And the Afghan War of 1878-80, with the massacre of the British envoy and his escort at Kabul in 1879, showed us the perils and difficulties of even a temporary and partial occupation.
