There are many things I should like to speak of, especially incidents and personalities connected with the battle, but am now too low spirited to relate them. We are so inconveniently situated, the wind and dust so disagreeable, and at times so concerned for our reputation, that often I become almost hopeless, and hardly care what becomes of me. The Indiana troops have truly been unfortunate, the 2d regiment especially. From our first entering the service, we were organized in a way contrary to our wishes, and officers selected for us, wholly unqualified for their stations, and even below mediocrity in point of talent, which rendered them unable to draw the attention of commanding officers to their regiment. Thus the greater portion of our time was spent in obscurity, wading the lagoons of Belknap--since which time we are nothing indebted to our regimental officers for our preferments. General Lane has made the 2d regiment what it is, and does honor to the position which he occupies. But I will cease this strain, as I promised to complain as little as possible. _April 1st._--We are now comfortably situated, and have less cause of complaint than at any other time during the service. There are two tents pitched together for our mess of eight, who live together in the greatest harmony. Our floor is carpeted with grass, and we have blankets and provisions in abundance. But still we look with much solicitude to the time when we shall meet our beloved friends at home. What a blank is caused by the absence of some of the refinements of society, and to be so long absent from those we love, with but little to occupy their places!--I have learned much in the tented field; I have learned how few are the real wants of man; I have learned to abstain from luxuries and to suffer privation; I have learned how important is good female society for the refinement of manners and the elevation of morals. All is quiet again, and the excitement attending the expectation of another attack, has died away. Until recently, the guard duty has been very heavy, and the troops in constant anxiety, caused by the rumors in circulation.--Yesterday the whole division passed in grand review before General Wool and staff. It was truly a splendid sight. Seven regiments of infantry, accurately dressed upon the same line; two squadrons of dragoons, and four batteries of flying artillery. The gaudy uniforms of the general and staff added to the imposing grandeur of the parade. The camp is generally in good health, and our wounded doing well. The loss of Goff and Robinson is a severe stroke to the mess. I assure you we miss them greatly, especially at night, when we see their vacant places upon the ground.
