BALTIMORE, May 16, 1864.

Major-General SIGEL,

In the Field:

The swelling of the rivers has somewhat impeded Grant's pursuit. He is waiting for re-enforcements, which are being sent rapidly. General Augur has gone to the front from Washington. All old regiments from Baltimore and Annapolis have gone forward, and their places filled by 100-days' men from the West. No fighting since Thursday of any consequence. Some accounts say Lee is falling back in the direction of Gordonsville instead of Richmond. Great many reports published are entirely unfounded or exaggerated, but no doubt exists of the general successful progress of our arms, though the losses are very great. Lynchburg reported as defend by works of strength and a reserve force. Baltimore rebels have it that Breckinridge and Morgan are both in Central Virginia, but exact position does not seem to be known.
