At 10.35 the flag-ship signalled to the _Monarch_, "Steam close in to the batteries we have silenced and drop a few shells into them at close range." This was followed by, "Go as close to forts as water will permit." The _Monarch_ then steamed in shore and poured in a tremendous fire from all her guns. At 11.30, there being no return fire, she, as well as the _Invincible_, ceased firing. At 11.40, the gunboats having returned from Marabout, the _Monarch_, which remained under way, was signalled to support them in an attempt to destroy the Mex works, but ordered not to fire unless fired upon. All the gunboats were at the same time signalled to close in to the batteries, and, remaining under way, to destroy their rifled guns. The _Condor_, ten minutes after, signalled that she had only twenty-one shells for each gun left, and received the order to cease firing. The gunboats, supported by the _Monarch_, continued to fire on the works. At 11.58, the _Monarch_ observing soldiers running back into the batteries, permission was given her to reopen fire. Permission was also given to the _Penelope_ to fire at the rifled guns in the batteries with her 40-pounders. At 12.20 p.m. the _Monarch_ ceased firing, signalling that she had driven about 200 soldiers out of the works. At 12.50 p.m. the _Penelope_ was ordered to get under way, and taking advantage of her light draught, to try to dismount the guns at Mex. She then weighed and proceeded in towards Mex Fort, firing at intervals. At 1.10 the windmills in the neighbourhood of the forts were seen to be full of soldiers, and the _Monarch_ was ordered to open fire on them with her light guns. About 2 p.m. the Admiral, seeing that the gunners of the western battery of Mex had abandoned their guns, and that the supports had probably retired also, landed a party, under cover of the gun-vessels and gunboats, who destroyed with gun-cotton two 10-inch rifled guns, and spiked six smooth-bore guns in the right hand battery. The party returned without a casualty beyond the loss of one of their boats, which got capsized on the rocks, on an alarm (happily unfounded) being raised that some soldiers were approaching to attack the little force. At 3.25 the _Penelope_ signalled to the Admiral that Fort Kamaria had its guns manned, though, from her inshore position, the ship's guns would not bear on them. The Admiral, in consequence, directed the _Penelope_ to change her position and open fire on the fort. About the same time soldiers were observed transporting light guns into one of the Mex batteries, and the _Monarch_ was signalled to attack again. Both vessels promptly responded, and, steaming into position, poured in a devastating fire on the points indicated. At 5.30, there being no reply from the enemy, the inside squadron ceased firing. This concluded the operations of the day.
