ST. LOUIS, Monday, July 20.
    An army officer just from Fort Larned, on the Arkansas River, says that from twelve to fifteen hundred Indians, representing nearly all the tribes on the plains, congregated at or near that post to receive annuities, but that on account of recent depredations Col. WYNCOOP had been ordered to withhold arms and ammunition. This the Indians alleged was a violation of the treaty, and they notified Col. WYNCOOP, that if he did not issue the arms and ammunition they would fight for them--that they were ready for war again. The meeting broke up in great confusion.
    That evening (the 10th inst.) the Kiowas attacked a train from Kansas City, also a Mexican train and mail carrier, and robbed them of supplies and provisions and beat the teamsters.
    Gen. SULLY arrived from Fort Harker on the 11th inst., and notified the Indians, in the presence of 600 cavalry, that he preferred peace, but was prepared for war. This seemed to awe them somewhat, but they were sullen and discontented.
    Col. WYNCOOP deprecates the vacillating course pursued by the Government, and says the Indians in his agency were never more peacefully inclined. But he says that hostilities are liable to break out at any time.
    A Lieutenant and five soldiers belonging to Fort Larned have been killed by the Indians.
    All the troops at Fort Ellsworth have been ordered to Fort Larned, and the commanding officers of all the posts in the department have been ordered to prepare their commands for action on the shortest possible notice.
    A Laramie dispatch says the Indians captured a hundred and thirty mules belonging to E. CREIGHTON, near Capon station, Saturday, and also drove away a large number of cattle, which they soon abandoned, however, evidently in fear of pursuit.
    The trains on the Pacific Railroad began running to Benton to-day.
