The 80th regiment came from Trincomalée, in Ceylon, a very unhealthy station, and where, during a five-years stay, they lost a very great number of men. This regiment was very healthy on landing. It was composed of what are usually termed old Indians; draughts from the 36th, 52d, 71st, and 72d, regiments, which had been sent home after a stay of fifteen or twenty years in India. The 80th suffered most of their loss after crossing the desert. At Ghiza, at El Hammed, and at Alexandria, they were the most healthy corps. However, there were many old men in this regiment who never recovered the fatigue of the march, nor the illness at Rhoda island, and who felt most severely the cold weather at Alexandria. A fact regarding this corps deserves mention. Mr Brown, who was in charge of it, informed me, that many men, who, at Trincomalée, were never free from liver-complaint, and were almost always in the hospital with this disease, never complained at Alexandria. This fact, on inquiry, I found held good in most other corps, and I had observed many instances of it in the 88th regiment. The 86th regiment landed in a healthy state. This regiment had been six years in a warm climate. They came from Bombay, where they had been in garrison for the two last years. They continued very healthy till they were encamped at Rhoda island; there, and at El Hammed, they suffered much: subsequently, no corps in the army suffered less or lost fewer. The frequent movements of this corps contributed to their being in a more healthy state than some other corps were. The 88th regiment had been about three years in a warm climate. They likewise came from Bombay. This regiment crossed the great desert with the loss of only one man. They were very healthy at Ghenné, and continued so till their arrival at Rhoda. The 88th was the first regiment from the Indian army that arrived at Ghiza, where they found the 89th regiment, and the ophthalmic hospital of the English army. In the course of the first week after their arrival at Ghiza, the 88th regiment sent one fourth of their strength into the hospital; all of them cases of fever or ophthalmia. At El Hammed, in proportion to the strength of this corps, ophthalmia prevailed more in it, and the regiment suffered more from it, than any other corps, except the 10th regiment. It will be remembered, too, that it was in the 88th regiment that the plague first broke out; and this regiment had more cases and more deaths from it than any other European corps. Mr Tonrey and myself, who attended these first cases, were among the few medical men who were exposed to the contagion and came in contact with the patients, and yet escaped the disease. The 88th regiment became at last one of the most healthy corps in the army. From the 1st December, 1801, to the 1st May, 1802, they only lost two men; of these, one was from the plague, and the other from sudden death, cause unknown.
