Forward now moved the compact scarlet lines to where the enemy’s force under the Shah Zadeh in person were drawn up to defend their camp on the left rear of the town of Mohammerah, and a desperate fight appeared about to open. Suddenly, almost as if by magic, the force disappeared. Paralysed by our fire, particularly by the size of the 68-pounder shots, and fearing awful consequences, the Shah’s terrible army turned and ran, and though the pursuit was engaged in for three or four miles, only a straggler or two was cut off. At night our cavalry returned, and reported that the enemy, at a distance of eleven miles, was still in full retreat.
Our troops bivouacked in line of battle, but such caution proved to be superfluous, and on the morning of the 27th the British army took possession of Mohammerah.
Stores of grain and ammunition, 18 handsome brass guns in good working order, arms of all kinds, and tents fell into our hands, for a total loss of 10 killed, with one officer, Lieutenant Harris of the Indian navy, and 30 wounded. The Persians had at least 300 killed, while many prisoners were taken.
These latter received every kindness, but for a long time were suspicious of their captors, expecting a fate which would probably have overtaken any of our brave fellows who might have fallen into Persian hands. Fortunately, such a contingency had not to be faced.
The town of Mohammerah, once a place of importance, was found to be a filthy collection of mud huts, and apart from its fortifications (where the guns had been admirably served, some of our ships suffering severely as a result), was found to be of little practical use. The moral effect of such a victory was enormous.
A small expedition under Captain Rennie was despatched up the Kanin river to reconnoitre, while the General fortified Mohammerah to the best of his ability before deciding upon a further plan of campaign.
By the 4th April, Captain Rennie’s expedition returned, and reported having seen the Persian army at Ahway. After a few shots, he had captured the town, together with immense stores of grain and powder, the Persian army again retreating with little show of fight. These operations were about to be turned to advantage by the commander-in-chief when a despatch was received announcing that peace with Persia had been concluded at Paris.
Accordingly, operations were at once commenced for evacuating Mohammerah, though the disappointment to all ranks was keen. By the end of May the evacuation was complete, though Bushire was held till October, when it was handed back to the Persians.
Apart from prestige, an important factor in Eastern politics, the Persian campaign of ’56 and ’57 may be said to have been of little practical use, but one good result accruing must not be overlooked. It prepared some, at any rate, of our troops for the tremendous struggle which was even then brewing in India.
