In October, 1861, he was in the field for five days with his regiment, within which time he participated in no battle, skirmish, or engagement of any kind.
After five days spent in marching and camping he was taken sick, and after remaining in camp six or seven weeks, his illness still continuing, he was granted sick leave and came to Washington.
In June, 1862, he was put on duty in the Commissary Department at Washington and remained there until August, 1863, when he was summoned before a retiring board convened for the purpose of retiring disabled officers.
From testimony before this board it appears that the illness which caused him to leave his regiment was one not uncommon in the Army, and yielded to treatment, so that in April or May, 1862, he was completely cured.
About this time, however, he was attacked with convulsions, which were pronounced by the physicians examined before the board to be a form of epilepsy, and for this cause he was found to be incapacitated for active service.
The medical testimony, while it suggested various causes for this epileptic condition, negatives entirely any claim that these attacks were at all related to the illness which obliged this officer to abandon service with his regiment. He testified himself that he had been told he had one or two convulsions in childhood, but there is no direct testimony that he was subject to epileptic attacks before he entered the Army.
The retiring board determined upon the proof that this incapacity did not result from any incident of military service, and therefore Lieutenant McBlair was in October, 1863, retired wholly from the service with one year's pay and allowances, which is the usual action in such cases, and which was approved by the President.
But in April, 1864, the President, in a review of the case, made an order that instead of this officer being wholly retired he should be placed upon the retired list as of the date when the action of the retiring board was originally approved.
For about twenty years, and up to April 30, 1884, he remained upon the retired list and received the pay to which this position entitled him.
Quite recently, in consequence of a claim of additional pay which he made upon the Government, his status was examined by the Court of Claims, which decided that the action of the President in April, 1864, by which he sought to change the original disposition of the case upon the findings of the retiring board, was nugatory, and that ever since October, 1863, this officer had not been connected with the Army and had been receiving from the Government money to which he was not entitled.
