The inclosed letter of my assistant adjutant-general, written on the 23rd instant, but received only on my arrival at the gun-boat point yesterday evening, confirms the information given in my last report. With the next steamer I will have the honor to submit a detailed report of the expedition.
Very respectfully, captain, your obedient servant,
Captain OLIVER MATTHEWS,
BARRANCAS, FLA., July 23, 1864.
GENERAL: A refugee just came from Fifteen-Mile Station and says Maury was telegraphed at Mobile, from telegraph station 5 miles above the Fifteen-Mile Station, to go there at once and engage you. He says the dispatch was sent yesterday morning, and that Maury has 1,300 strong, including a light battery of six guns. Excepting the battery Maury's force consists of cavalry. The refugee informs us that you surprised the Seventh Alabama at Fifteen-Mile Station and captured their horses, &c. Nothing new of importance here. No arrivals from New Orleans. All quiet.
Very respectfully, your obedient servant,
