P. Heintzelman to Daniel Tyler, June 17, 1863

General DANIEL TYLER, Sandy Hook: Your dispatch of 11 a. m. received, for which I render you many thanks. I cannot feel that the enemy is withdrawing from the river, and the movement only admits of satisfactory solution on the supposition that he has no considerable force in this district. If it was only a feint to conceal a movement in another direction, he is prob-, ably falling back. If Longstreet’s and Ewell’s corps have been at Winchester at all, they are now somewhere in that eel I hope you will keep out all of your cavalry until we find out his whereabouts. I have directed mine to feel up to him, and they are now hard at work. HOOKER, Major-General. BaALTImMorE, Mp., June 17, 1863—12.30 p. m. Brigadier-General Briaas, Relay House, Mad.: Keep one section of the battery to protect the bridge. Send the rest here. Have you afull battery; and have you sufficient ammunition ? W. M. H. CHESEBROUGH, Assistant Adjutant-General. BALTIMORE, Mp., June 17, 1863. (Received 12.30 p. m.) H. W. HALLECK, General-in-Chief : No other information than that contained in Tyler’s telegrams, which, I believe, are taken off for your benefit. General Tyler and forces are on Maryland Heights. ROBT. C. SCHENCK, Major-General. BALTIMORE, M. D., Jwne 17, 1863. Brigadier-General TyLEeR, Sandy Hook : Major-General Milroy, with his staff, returns to Harper’s Ferry as a volunteer, you still retaining command. You can probably spare Captain Woodhull. I need his services, and desire yim to return here by the first good opportunity. ROBT. C. SCHENCK, Major-General. BALTIMORE, Mp., June 17, 1863. (Received 12.30 p. m.) H. W. HALLEcK, General-in-Chief : Can one or two of the militia or volunteer regiments coming on from New York or Massachusetts be given me temporarily here? I have but one regiment of infantry here. The Thirty-seventh New York Militia, Colonel Roome, is ready to move to-day. That regiment was formerly stationed here, and could do good service in any emergency on the north side of this city. I think we shall be able to do something to-day toward organizing extempore militia. ROBT. C. SCHENCK, Major-General. BALTIMORE, Mp., June 17, 1863—12.30 p. m. I find it necessary to put the One hundred and fiftieth New York into Fort Marshall. That fort commands both the others and the city, and the garrison must be kept up. It would take at least 20,000 men to hold the approaches or commanding points around the city; so in case of a raid I shall rely on being prepared to make barricades at the entrances of streets, and the local force I can raise and arm can hold them. I still doubt if the marauding rebel foree which General Couch reports in Pennsylvania will visit Baltimore, though they might get near enough to make a dash. Communication with Harper’s Ferry is resumed. The two regiments I sent, Fourteenth New Jersey and One hundred and thirty-eighth Pennsylvania, have arrived there, and I now feel easy about the place. Milroy, whom I ordered here, returns to his troops as a volunteer, under General Tyler. ROBT. C. SCHENCK, Major-General. BALTIMORE, M. D., June 17, 1863. (Received 2.14 p. m.) H. W. Hawweck, General-in-Chief: My scouts at South Mountain House, 13 miles from Hagerstown, report 100 of the enemy’s cavalry at Hagerstown, and that there is no infantry on this side of the river. ROBT. C. SCHENCK, Major-General. JUNE 17, 1863—1.05 p. m. General DANIEL TYLER, Sandy Hook : Can you give me positive and ‘correct information of any force of any kind and number of the enemy at any particular spot ? From all reports here, we might conclude that he covered all Western Pennsylvania and Maryland, or that he was not thereat all. Can ou give me anything correct ? ae JOSEPH HOOKER, Major-General. MaryYLAND Heicuts, Mp., June 17, 1863—6 p. m. Major-General ScHENcK, Baltimore, Md.: Iam requested by Major-General Hooker to see to our infantry guard at Noland’s and Hauling Fords. This is out of my command. Will you attend to it ? DAN. TYLER, Brigadier-General, Commanding. 182 N. ©, V. A. W. V. A., M. D., P. A., ETC. (Cuar, XXXIX. BALTIMORE, Mp., June 17, 1863. (Received 9.50 p. m.) Major-General HALLECK, General-in-Chief : Has General Heintzelman the country patrolled about Poolesville and-in toward Annapolis Junction? It ought to be. I have no cavalry to send in that direction. Eight rebel cavalry came up from the Potomac last evening, and visited the railroad station next this side of Mount Airy, 40 miles from Baltimore. They alarmed the people, but only asked for news. They were evidently out on a scout to get information. ROBT. C. SCHENCK, Major-General. JUNE 17, 1863—10.30 p. m. General DANIEL TYLER, Sandy Hook: A force of cavalry, with two regiments of infantry and a bridge train, are ordered to the mouth of the Monocacy, via Washington, from this army. They will be there to-morrow morning. Fitz. Lee’s brigade of cavalry were driven out of Aldie by our cavalry this afternoon. Stuart is reported at Middleburg. Their presence there may indicate Noland’s Ford or that vicinity as a point of crossing. Please see that our infantry guard Noland’s and Hauling Fords. DANL, BUTTERFIELD, Major-General, Chief of Staff. Washington, June 1%, 1863—11.45 p. m. General SCHENCK, Commanding, &c., Baltimore, Md. : I have the country patrolled above Poolesville and along the Potomac as high as the Monocacy on this side, and have scouts out onthe other toward Leesburg, but no patrols in toward Annapolis Junction. The railroad is guarded by a regiment of infantry as far as the Junction. The rebel cavalry must have crossed the Potomac above the mouth of the Monocacy. I see no necessity for any patrols in the rear of my troops.
