Amite in time, and while making a feint of bringing and crossing that stream he reports that he was assailed by an enemy's force from the opposite bank, but my opinion is that the force there was not large.
I t is my intention to hold Manchac Pass and as much of the railroad beyond of some importance to the defense of the city, and to this end the troops are now throwing up a breastwork, in order to hold the defile leading from the Pass to Ponchatoula against any reasonable force the enemy would attempt a raid with.
In the mean while I respectfully silicic the attention of the general commanidng to the importance of having the great bridges across both Passes repaired at an early day, so that in case of successes of greater importance we shall be ready to push cars beyond without delay. The work required on these bridges is large.
