Talking about the press while I was searching I saw an article about Anderson from Fort Sumter. The article said he became destitute after the war and they (the press) accused Grant of looking out for other political interests instead of Anderson.
The following is a quote from Anderson's biography in Cullum's Register. It appears the he was in very poor health, but probably not destitute since Anderson and his wife were in Europe seeking to regain his health.
"President Lincoln, in recognition of Anderson's services, appointed him, May 15, 1861, a Brigadier-General in the Regular Army, and placed him in command of the Department of Kentucky, and subsequently of that of the Cumberland, which his shattered health compelled him to relinquish in the following October. From this time till his retirement from active service, Oct. 27, 1863, he performed no duty except for a short period in command of Fort Adams, Newport harbor, Rhode Island. However, to entitle him to full pay, the Government generously gave him a nominal position on the staff of the General commanding the Eastern Department, which continued until terminated by Army regulations and law. On Feb. 3, 1865, he was brevetted a Major-General "for gallant and meritorious service in the harbor of Charleston, S. C., in the defense of Fort Sumter."
In 1870 he went abroad, first to Dresden, then to Tours, and finally to Nice, hoping for relief in the mild, congenial climate of Southern France; but his health was so broken by his long service and severe wound in the Army, and his constitution so shattered by the hardships and anxiety he had endured at Fort Sumter, that death in his sixty-seventh year at last came to end his sufferings."
