one
o'clock
One gun of the Penelope had been disabled , and two of the Alexandra . Only five men had been killed , altogether , and twenty-seven wounded . No sign was made of surrender , and an occasional fire was kept up on the forts , to prevent the Egyptians from repairing damages . At one o'clock , twelve volunteers from the Invincible started to destroy the guns of Fort Mex . Their fire had ceased , and no men were to be seen in the fort ; but they might have been lying in wait to attack any landing party . On nearing the shore , the surf was found to be too heavy for the boat to pass through it , and Major Tulloch and six men swam ashore and entered the fort . It was found to be deserted , and all the guns but two ten-inch pieces dismounted .
