On May 9 the British force advanced to Er-Rahmaniyeh where French General Lagrange had taken post with the intention of holding firm. At 10 am Royal Marines and sailors under Captain Curry with four boats and three armed launches commenced an attack upon the French forts at Er-Rahmaniyeh and at 4 pm were supported by Ottoman gunboats and soon the French made a general retreat towards Cairo leaving in the fort 110 of their sick and wounded. A French detachment of fifty cavalry from Alexandria were taken at the same time and with this they were effectively cut off with all communication between there and the interior of Egypt; the allied forces suffered only five killed and 26 wounded.
