The following is a letter written by Alonzo ("Lon") Davenport of the 16th New Hampshire Infantry, to his wife Emily "Em". He had enlisted on 3 Sept 1862, and was mustered in on 23 Oct as a corporal. He was mustered out on 20 Aug 1863.

It is a very short letter, as his captain [Jonathan P Sanborn] was heading into town, so Alonzo was quick to write.

Alonzo D Davenport was born in Chelsea, Vermont on 4 Nov 1835, the son of Davis L. and Submit (Courser) Davenport. He was living in Salisbury, New Hampshire at the time of his enlistment, and afterwards moved to Franklin, NH. He died there from Bright's Disease on 28 June 1906, aged 70, and was buried in Franklin Cemetery.
He had married his wife, Emily A. Davis, on 16 Mar 1860. She died in Franklin on 2 Feb 1919.

The Battle of the Crater, aka "Burnside's Mine", took place on the 30th of July, 1864, near Petersburg, Virginia. With a siege of the city having just begun, a plan was devised to break through the Confederate lines by mining under a section of their defenses, and blowing it up with explosives.

The attack began at 4:44 am, when the mine exploded, leaving a 200 foot long, 50-60 foot wide crater in the line, some 25 to 30 feet deep in places. A division under General Ledlie led the attack, and marched straight into the hole in the line. They were to continue on towards Cemetery Hill, but were bogged down within the crater. Two other divisions followed them in, to occupy the grounds on both flanks of Ledlie, while he continued forward.

Several New Hampshire regiments were a part of the 2nd Division, 2nd Brigade, of the IX Corps: the 6th, 9th and 11th Infantry Regiments. They followed the 1st Division into battle, and went to the right of the crater, in an attempt to reach the high ground of "Cemetery Hill" (Blandford Cemetery). 

It did not take long before the Confederates were able to recover from the explosion, and attacked the Union forces. With many of the troops still within the crater, and more marching into it, the soldiers were caught in a crossfire, with no where to go. Shortly after noon, the order was given to fall back to the Union lines. The losses for the day were around 4400 dead, wounded, and missing, all but 100 of them from the IX Corps. 

​Aylings Revised Register listed the number of killed and mortally wounded of the NH units as follows:
6th NH Infantry: 1 officer and 8 enlisted men
9th NH Infantry: 1 officer and 22 enlisted men
11th NH Infantry: 22 enlisted men

The 4th NH Infantry, which was part of the X Corps (attached to the XVIII), suffered 13 dead in the battle.

Located in a plot at the Arbor Street entrance way to the Exeter Cemetery stand two stones erected in 1964 as memorials to those men with ties to the town of Exeter, NH  who served in World War II and the Korean War (the latter tablet now includes the Vietnam War veterans). They share the plot with the boulder and plaque of Gen Gilman Marston, a Civil War veteran.
Those ​names in blue indicate a link to their Find a Grave memorial page, most of them giving much detail about the soldier's service and the cause of their death in the line of duty.

Located on Nimble Hill Road, just south of the town library, stand three stone memorials for those who served from Newington in our country's wars.

The oldest one (on right) was erected by the Shakesperian Club in 1926, followed by the World War II monument (left) in 1949 by the Newington Veterans Association. The center stone represents those who served during the Korean War (no date is inscribed on this one).  

Erected by the Newington Veterans Association
1949

I didn't get a separate close-up photograph of the World War II Memorial, so hopefully I got the above names transcribed correctly. On the tablet, the names are listed surname first, which I changed here.

The transcription of the oldest memorial can be seen in an earlier post here:
