All the stores, guns, and ammunition which could not be carried off having been destroyed, the army commenced its return march to Bushire on the 7th, not expecting to encounter an enemy.
After moving a few hundred yards clear of the intrenchment, the troops were halted to witness the explosion of a large quantity of gunpowder, stated to be 36,000 pounds. A very magnificent spectacle it occasioned. The evening was darker than usual, and the rush of one mighty column into the heavens, with cloud over cloud of bright silvery-looking smoke, mingled with shells bursting like sky-rockets in the midst, attended by a report that made the hills echo again, and a concussion which shook the ground even where the advanced guard stood, formed altogether an event not likely to be forgotten by any who beheld it. The pile of ammunition was fired by Lieutenant Gibbard, of the Horse Artillery, and Lieutenant Hassard, the adjutant of the 2nd European Light Infantry, with rifles and shell-bullets of Colonel Jacob’s invention, from a distance of about 150 yards. Both were thrown down by the shock of the concussion. From Outram and Havelock’s Persian Campaign, by Captain Hunt, from which the account of the battle of Khoosh-Aub is chiefly taken.
The march was then renewed, the general belief being that the enemy were never likely to approach them. At midnight, however, a sharp rattle of musketry was heard, and it was supposed that the rearguard were attacked. Colonel Honnor so ably handled the protecting troops, that he kept the enemy at bay for some time. In about half an hour, however, after the first shots had been fired, the Persian cavalry advanced in great numbers, and the entire force was enveloped in a skirmishing fire. Horsemen galloped round on all sides, yelling and screaming like fiends, and with trumpets and bugles making all the noise in their power. One of their buglers got close to the front of a skirmishing company of the Highlanders, and sounded first the “Cease fire,” and afterwards “Incline to the left,” escaping in the dark. Several English officers having but a few years before been employed in organising the Persian troops, accounted for their knowledge of the English bugle-calls, now artfully used to create confusion. The silence and steadiness of the men were most admirable, and the manoeuvring of regiments that followed, in taking up position for the remaining hour of darkness, was as steady as on an ordinary parade; and this during a midnight attack, with an enemy’s fire flashing in every direction, and cavalry surrounding, ready to take advantage of the slightest momentary confusion. At length, having been roughly handled by the 78th, the cavalry, and horse artillery, the Persian horsemen kept at a respectful distance.
The army was then thrown into an oblong form—a brigade protecting each flank, and a demi-brigade the front and rear; field-battery guns at intervals, and a thick line of skirmishers connecting and covering all; the horse artillery and cavalry on the flank of the face fronting the original line of march, the front and flanks of the oblong facing outwards; the baggage and followers being in the centre. When thus formed, the troops lay down, waiting for daylight in perfect silence, and showing no fire or light of any kind. Sir James Outram met with a severe accident while carrying out these admirable arrangements; but they were well concluded by Colonel Lugard, the chief of his staff.
Scarcely was the formation completed, than the enemy brought five heavy guns to bear; and iron shot plunging into the 64th Regiment, knocked down six men, and killed one of them. Another shot, first taking off a foot from Lieutenant Greentree, severely wounded Captain Mockler of that regiment. Several of the camp followers and baggage animals in the centre were killed but the orderly conduct of the troops saved them from many casualties, and as no musketry fire was allowed after the guns opened, the enemy had no opportunity of improving his original range.
As the morning approached, the enemy’s fire slackened, and it was believed that he had retreated; but as the mist cleared off, the Persians were seen drawn up in line, their right resting on the walled village of Khoosh-Aub and a date-grove, their left on a hamlet with a round fortalice tower. Two rising mounds were in front of their centre, which served as redoubts, and where they had their guns; and they had some deep nullahs on their right front and flank thickly lined with skirmishers. Their cavalry, in considerable bodies, were on both flanks. Soojah-ul-Moolk, the best officer in the Persian army, was at their head. The British army was drawn up in two general lines. The front line consisted of the 78th Highlanders, and a party of sappers on the right; then the 26th Regiment of Native Infantry, the 2nd European Light Infantry, and the 4th Rifle Regiment on the left of all.
The second line had Her Majesty’s 64th Regiment on its right, then the 20th Regiment Native Infantry, and the Beloochee battalion on its left. The light companies of battalions faced the enemy’s skirmishers in the nullahs, and covered both flanks and rear of their own army. A detachment of the 3rd Cavalry assisted in this duty; and as the enemy showed some bodies of horse, threatening a dash on the baggage or wounded men, they were of considerable service.
The lines advanced directly the regiments had deployed, and so rapidly and steadily did the leading one move over the crest of the rising ground (for which the enemy’s guns were laid), that it suffered but little; the Highlanders not having a single casualty, and the 26th Native Infantry, their companion regiment in brigade, losing only one man killed, and but four or five wounded. The brigades in the rear, in consequence of the shot which passed over the regiments in front striking them, suffered far more, especially the 2nd European Light Infantry.
During this time the cannonade had been continuous; but as the Persian fire in some degree slackened, the British artillery advanced to closer action, making most beautiful practice, and almost silencing the opposing batteries. Some bodies of horse soon presented an opportunity for a charge, and the squadrons of the 3rd Cavalry, and Tapp’s irregulars, who had hitherto been on the right front, dashed at them, accompanied by Blake’s horse artillery, and made a sweeping and most brilliant charge, sabring gunners, and fairly driving the enemy’s horse off the field. The 3rd Bombay Light Cavalry was led by Lieutenant-Colonel Forbes. Lieutenant Moore, the adjutant of the regiment, was, however, perhaps the first of all, by a horse’s length. As the regiment approached the enemy, thrown into a somewhat disorderly square, his horse sprang into their centre, but instantly fell dead, crushing his rider, whose sword was broken by the concussion. The enemy pressed round him, but speedily extricating himself, he attempted with his broken weapon to force his way through the throng: he would most certainly have lost his life, had not Lieutenant Malcolmson, observing his danger, fought his way through the crowd of Persians, and, giving him his stirrup, carried him safely out from among them. The thoughtfulness for others, cool determination, devoted courage, and ready activity shown in extreme danger by this young officer, Lieutenant Malcolmson, were most admirable. Both these officers most deservedly gained the Victoria Cross.
Meantime, the infantry lines were still advancing rapidly, and in beautifully steady order, to sustain the attack, and were just getting into close action when the enemy lost heart, and his entire line at once broke, and fled precipitately. The men cast away their arms and accoutrements, and, as the pursuit continued, even their clothing. Two or three of the sirbar, or regular battalions, on the extreme right, alone retired with any semblance of order. The 3rd Cavalry
