observable. We heard, however, very distinctly the incessant movement of railroad trains.
The final chapter of the “siege” forms a curious tale, partaking more of the ludicrous than of the horrors of war. In some way the impression prevailed at all the headquarters that the enemy was about to strike a great blow. Halleck issued an order enjoining the greatest caution in feeling the enemy. Sherman was even told, if the risk in holding his new position was too great, to fall back. The apprehension of a rebel attack en masse grew stronger in the course of the 29th. The continuous rolling of trains was construed as meaning a concentration of forces at certain points for that purpose.
