The following is a letter written by Alonzo P. Moulton of Co. H, 27th Maine Infantry, to his sister Lucy E. (Moulton) Perry of Cornish, Maine. The envelope was postmarked on Dec 25th 1862, at Alexandria, VA. 
[I left spelling errors as is. There were no periods to break up the sentences so I did add a few to help in reading this. Some lines did have either a question mark or exclamation point, but hard to tell the difference.]

Dear Sister
   I received your kind letter to day and as I have not much to do this afternoon I will write to you. I am as well as common all excepting one thing and that is I cant speak one word. I got cold out on picket and had a sore throat the cold has left me now but I cant talk any only whisper I can do that as well as once my throat is not sore now and I dont see why I cant speak do you? It has been two weeks since I spoke one word but I guess that I shall get well of it soon I hope so any way for it is not very pleasant to have to talk in a whisper all of the time I guess that it is nothing but hoarseness.
   I have heard of quite a number that has been takin the same way that was out here in the army and some of them did not get over it untill they went home? I dont have to do any duty now but I had rather be all right and do duty than to be as I am now if I dont get any better I shall stand a chance to get sent home before long but I think I had rather stop and run any risk than to leave the boys although it is a pretty hard show but as long as I am well I am good for it you now(?) We have moved since you heard from me before we are down the lines further now and about 12 miles from Washington and two miles from Alandra [Alexandria] and about five miles from Mount Vernon. I have not been down yet but mean to as soon as I can. I passed the house that Col Elsworth was killed in the other day ! dont you think we got winter quarters most all done at Camp Seward and had to leave then that was so bad I think? We have got the worst place for a camp ground that you ever saw all around with stumps but it is quite a sitely place as it is so near the Potomac that we can see all of the shipping that passes. We saw one of the gun boats pass down the river this morning the men that stood on it looked just as though they stood on the top of water they said that it was the monitor it had been up to Washington! I must close now!  you must not worry about me for I shall come out all right!
                                                                      Your loveing Brother Alonzo

I dont know as you can read this for there is not a drop of ink in the camp so I have to write with a pencil. We have not got any captain yet nor chaplain. I guess that Eld Russell will be chaplain I hope so

Pg 1 note: Alonzo writes (in sideways notation on top) that "we" have no captain or chaplain. Capt. Henry Snow of Company H had resigned in Nov '62, as he had wanted to be the regimental chaplain (he was a minister in Cornish), but not getting the approval of the other officers, quit instead. "Eld Russell" was Otis F. Russell, a corporal in Co. H, who was a Freewill Baptist minister before joining the service. He would get the promotion on Jan 30th, 1863.

Pg 3 note: "Col Elsworth" - Col. Elmer E. Ellsworth was the first Union officer killed during the war, while attempting to take down a Confederate flag atop the Marshall House in Alexandria, Virginia (24 May 1861).

Alonzo P. Moulton survived the war, and went on to reenlist with the 2nd Maine Cavalry in Oct 1864, serving for a year. A lifelong resident of Parsonsfield, he married Mary E. Towle after the war, had four children, and lived as a farmer in South Parsonsfield. He died in 1885, and was buried in the Maplewood Cemetery.

During his time with the 27th Maine, Private Charles Gooch, of Company I, wrote over fifty letters to his wife Julia, back home in Kennebunk, Maine. The following is a letter he wrote to her on the 15th of January 1863. I've transcribed it as written, with lack of punctuation and spelling errors included.

Notes:
(pg 1) "Theodore" is Theodore Gooch, a cousin of Charles W Gooch, who also lived in Kennebunk. His full name is mentioned in an earlier letter.
(pg 2) The Christian Watchman and Reflector was a Baptist newspaper style weekly periodical, printed in Boston, MA. The article mentioned by Charles was likely from the Dec 25th issue (viewable on Genealogy Bank w/ subscription), which included a letter written by a soldier at Fort Albany, describing the 27th Maine (and other units) marching onto the grounds.
   (fath) = perhaps he meant "faith"? As he wrote this word on both ends of the sentence where he declined the offer of milk, was he fibbing about already having coffee that morning? Charles was a religious man, so perhaps he felt bad about lying to the Irishman and wife, so called that out in his letter.
(pg 4) "Isaac" is Sgt Isaac Emery of Kennebunk, who was the brother of Charles' wife Julia.

On December 9th, 1862, John H. Came wrote home to his sister, Miss Eliza C. Came, of West Buxton, Maine. He was a 1st Lieut. in Company C, 27th Maine. He died while serving in this regiment, on 16 Jan 1863, from typhoid fever. His body was returned home, and buried in the family cemetery in Buxton. He didn't marry.

Above is an 1861 map of Washington and Alexandria. Lieut Came wrote from Camp Seward, which was located somewhere along Arlington Heights. Bailey's Crossroads and Munson's Hill, where Co. C had done picket duty, is highlighted to the left of map. Camp Casey, where Lt Came would pass away in Jan 1863, was located south of Fairfax Seminary, northwest of Alexandria. Camp Vermont, where the regiment had spent the latter part of December '62, was just south of red arrow marked at bottom of map.

NOTES:
Page 1
Sister Eliza C Came, daughter of Abraham L and Annis (Green) Came, was born 1833 in Buxton. She never married, and died in 1885. She is buried in the Came family cemetery. 
Page 2
"Warren" is referring to Joseph F Warren, also of Co C, who was 2nd Lt. at the time of this letter writing. Following John Came's death, he became 1st Lt (and later captain, when John Hill was promoted to major).
Page 4
"Sam Davis" - I believe this is Samuel L Davis of Standish, Maine, who was captain of Co K, 25th Maine Infantry. He was "discharged for incompetency" on Dec 8th 1862 [according to ME archives index card].
There is also has some newer writing along the top that erroneously listed John's death as "Dec 16th", instead of Jan 16th.

​Frank C Came, of Co B, the fellow from York, was indeed Charles Came's son. I haven't trace their ancestry to see if or how closely related they may have been.
