Mvteki£»* ur the Arut.—\\ find this in lilt St. Louis Republican uf lust Friday:A correspondent yesterday alluded lo the circutnstaiKe of a female having been discovered iu l lie character of a.soldier, at Fort Mann the headquarters of the Indian battalion under Col. Gilpin. Another letter informs us that this woman was regularly mustered into service as a member of Capt. Uoltzscheizter’s company, from St. Louis, at Fort Leavenworth.—The company to which slie was attached leftFori Leavenworth on tbeTthof October, andshe remained with it until the denouement tookplace, late in November. It is said that she was enrolled as a private, under the patrullage of one of the Lieutenants of ibe company, and that she was afterwards detailed as a cook to the Lieu tenants* mess, remained in that situation until the '28th of November, when she was discharged from the army,and took up her march home in a return train, still iu her male I attire. It was afterwards discovered that herI discharge was irregular, and that some diftieul-j ty might grow out of it. Lt. O'Hara was there-I upon ordered to go in pursuit of the girl and bring her back. The trains were then four or five miles ahead, but were overtaken next day. Some resistance was offered by the teamsters toa aeperation from the soldier—as she still pretend d to be—and it was only the cofession of her sex and the determination of the Lieutenant to take her back as a regular enlisted soldier that they yielded. On her return, she stated the fuels connected with her introduction inio tii army as a soldier, and the part which she alleged Lieut Schnabel had acted in it. Thereupon the brothers Schnabel were put under arrest, and were waiting the return of Col. Gilpin, when they will have to answer thecharge of making a false muster roll, without a surgeon s examination. Meanwhile, the girlwas going at large about tin- Fort, as lively aspossible. She continued to dress in hrr uniform. of which she had draw u every necessary article; and it h added that she stood the fatigues of ilu: campaign as well or better thanmost of the able-bredie.il men of the battalion.One of our German papers published what purports to be a note addressed bv one of the Lieutenants to this damsel, which is suflicien-lv romantic and love-like, but it failed to reachher,and the bearer a corporal in company E, was imprisoned in attempting to deliver it.—Can this be taken asa fair sample of tie state of murals in this branc h of our army?
