It is a tribute due to the gallant subordinates of the fleet and land force to say, that, throughout their arduous duties, they evinced a courage and perseverance worthy of their country and their cause. While history is bound to publish truths, it never ought to extenuate the errors of any branches of its subject. By the 16th of April some hundreds became sick from exposure to the weather, the heavy rains that periodically set in about this time, and the scanty supplies of water; among whom were many of the principal officers. Upon the 23d and 24th, Councils of War were held, which decided upon an immediate re-embarkation. Captain Knowles of the Navy, who had throughout bore a distinguished part in the duties of an Engineer, was now entrusted with the demolition of Castillo Grande, which was with much labour completed on the 25th, and all the guns rendered unserviceable. The same was effected at Bocca Chica. Upon the whole, the Spaniards sustained a heavy loss, as appears from the following detail: _Guns_ Bocca Chica Castle 80 Fort St. Joseph 20 Fort St. Philip 15 Fort St. Jago 6 Fascine batteries on Barradera side 20 Four men of war at Bocca Chica 332 Two batteries at Passe Cavalla 13 Castillo Grande 63 Port Mazinello 12 Seven galleons 128 Conqesadon and Dragon men of war 134 ---- 723 ==== Such events to the enemy were for some time irretrievable, and long felt. The charges of repairing the different fortifications must have been prodigious, when we consider the strength with which they were constructed. Our loss upon the whole was undoubtedly great, being in all nearly two thousand men, and I annex a detail of the Officers of European Corps who were killed, died of the diseases incident to the climate, or of the wounds they received: WENTWORTH'S Regiment of Foot. _Killed_ _Died_ Lieut.
