On this occasion his force comprised the 65th (York and Lancasters), the 1st Bombay European Battalion (now the 2nd Royal Dublin Fusiliers), the 1st Battalion of the 7th Regiment of Bombay Native Infantry, and the flank companies of the 1st Battalion of the 2nd, 2nd Battalion of the 2nd, 1st Battalion of the 3rd, and 1st Battalion of the 4th Regiments of Bombay Native Infantry, with the Bombay Marine Battalion (121st Pioneers), together with 200 Bombay artillerymen. H.M.S. _Topaze_, _Liverpool_, _Eden_, and _Curlew_ also accompanied the force. The Arabs were in a most defiant mood. They had inflicted a severe defeat on a native force which had been sent against them a short time previously. This force had been driven back, with a loss of nearly 400 sepoys killed, whilst five British officers were amongst the slain. Sir Lionel Smith's force landed without opposition under cover of the guns of the fleet, and on March 2 the stronghold of the Joassma tribe was carried, after a sharp fight. The Imaum of Muscat now endeavoured to induce the tribes to come to terms, but on the 10th they made a most determined attack on our camp. In this they were worsted, but our losses were considerable, the 1st Bombay Fusiliers and the 7th Regiment of Bombay Sepoys (now the 113th) suffering severely. The destruction of their forts and vessels by the fleet soon reduced the Arabs to reason, and they agreed to send hostages to Bombay for their future good behaviour. Our casualties during this expedition were as follows: CASUALTIES AT BENI BOO ALLI. +-------------------------+-----------+-----------+ | |_Officers._| _Men._ | | _Regiments._ +-----+-----+-----+-----+ | | K. | W. | K. | W. | +-------------------------+-----+-----+-----+-----+ |Royal Navy | 3 | 3 | 5 | 20 | |65th York and Lancaster | - | 2 | 4 | 35 | |2nd Dublin Fus. | 1 | 3 | 17 | 34 | |113th Pioneers (British) | 1 | 2 | - | - | |113th Pioneers (Native ) | - | 2 | 21 | 122 | +-------------------------+-----+-----+-----+-----+ ADEN, 1839.
