Whilst these precautions against internal revolt were taken by the Shah and his unscrupulous minister, actively and unceasingly they laboured to defend the city against the enemy advancing from without. The fortifications now began to bristle with armed soldiers. The hammer of the artificer rang upon the guns in the embrasures. The spade of the workman was busy upon the ramparts. Eager for the foray, the trooper mounted his horse and scoured the country to cut off stragglers. But still the Persian army moved forward in that compact and well-ordered mass which had baffled the efforts and kindled the indignation of marauders along their whole line of march. Soon the contest actually commenced. On the 22nd of November, the advanced guard of the Persian army took up its position on the plain to the north-west of the city. Watching its opportunity, the Afghan horse charged the enemy’s cavalry with success, and then fell upon an infantry regiment, which stood firm, and repulsed the attack. The Persian field artillery opened briskly upon the Afghan force. A couple of guns in the city replied to them; whilst a party of Afghan horsemen, dismounted, crept under cover, and with their long rifle-barrelled matchlocks, fired on the Persian gunners. Upon this, skirmishers were sent out by the Persians, who turned the flank of the Afghans, and forced them back to the position which they had taken up before. No advantage was gained by either party. But the contest was now fairly commenced. The following day witnessed the opening of the siege of Herat—one, whether we regard the protracted nature of the operations, the vigour of the resistance, the gallantry of the chief actors concerned in it, or the magnitude of the political results, of the most remarkable in modern history. It was on the 23rd of November that the siege actually commenced. Taking possession of all the gardens and enclosures to the west of the city, and establishing themselves in considerable force among a cluster of ruins that afforded them good shelter, the Persians began to make their preparations for the attack. The garrison sallied out as they advanced. The Afghan infantry disputed every inch of ground, and the cavalry hung on the flanks of the Persian army. But they could not dislodge the enemy from the position they had taken up; and after carrying off a few prisoners, were compelled at last to retire.
