AUGUST 12TH.—There is trouble with Mr. Tochman, who was authorized to raise a regiment or so of foreigners in Louisiana. These troops were called (by whom?) the Polish Brigade, though, perhaps, not one hundred Polanders were on the muster-rolls; Major Tochman being styled General Tochman by “everybody,” he has intimated to the President his expectation of being commissioned a brigadier. The President, on his part, has promptly and emphatically, as is sometimes his wont, declared his purpose to give him no such commission. He never, for a moment, thought of making him more than a colonel. To this the major demurs, and furnishes a voluminous correspondence to prove that his claims for the position of brigadier-general had been recognized by the Secretary of War.
