Notwithstanding the modern rage for exploration, but few of our countrymen have hitherto pierced the stupendous barrier of the Paropamisan range; but the works of Hanway, Forster, Moorcroft, and Trebeck, Masson, and Sir Alexander Burnes, convey most valuable information concerning the wild regions through which they travelled, and I am bound in simple honesty to confess that my little book does not aspire to rank with publications of such standard merit. An author's apology, however humble and sincere, is seldom attended to and more rarely accepted. Surely I am not wrong in assuming that a feeling of mournful interest will pervade the bosom of those who have the patience to follow my perhaps over-minute description of places whose names may be already familiar to them as connected with the career of those bold spirits who in life devoted their energies to the good of their country and the advancement of science, and who in the hour of disaster, when every hope was dead, met their fate with the unflinching gallantry of soldiers and the patient resignation of Christians. My lamented friend, Lieutenant Sturt, of the Bengal Engineers, was one of the foremost of those who endeavoured, during the critical situation of the Cabul force previous to its annihilation, to rally the drooping spirits of the soldiers; and without wishing in any way to reflect on others, it may fairly be said that his scientific attainments and personal exertions contributed not a little to those partial successes, which to the sanguine seemed for a moment to restore the favourable aspect of our military position. But I forbear from now dwelling upon these circumstances, lest I might undesignedly give pain to those who still survive the fatal event, merely stating my humble opinion that the memory of any mistake committed, either in a political or military light, will by the noble-minded be drowned in sorrow for the sufferings and death of so many thousands of brave men.
