GARDINER — Lt. Henry A. Hobart was only 22 when he was killed in the War of 1812 during the battle of Fort George in Canada.

The Gardiner native and grandson of Maj. Gen. Henry Dearborn was the first Maine man to graduate from the Military Academy at West Point, the first officer from Maine to have been killed in action in the conflict, and the only period officer from Maine to have a military installation in the state named after him — Battery Hobart at Fort Williams in Cape Elizabeth.

The location of Hobart’s remains are unknown and apparently, no memorial stone was erected for and dedicated to him, until Sunday.

Members of Gardiner’s Christ Episcopal Church, along with veterans and others, dedicated a granite stone in Hobart’s honor in St. Ann’s Burying Ground adjacent to the stone of his mother Sophia Hobart, and aunt Pamela Dearborn Gilman, who died in 1814 and 1799, respectively.

It was a solemn ceremony, with the Rev. Kerry Mansir recalling the documented history surrounding Hobart’s death on May 27, 1813.

Mansir told the group of about 25 that turned out for the ceremony that historian Larry Glatz of Scarborough told her about Hobart’s story last December and asked if the church would be interested in asking Veterans Affairs to create a centograph for Hobart, to be placed next to his mother’s, as his remains were never identified and he had no burial site.

Hobart was the son of Dudley Bradstreet Hobart and Sophia Dearborn Hobart who was Gen. Dearborn’s daughter, said Mansir, reading from a history given her by Glatz. After growing up in Gardiner, Hobart entered the Military Academy at West Point in 1808 and graduated in 1811.

“Sadly,” Mansir said, “he holds the distinction of being only the second graduate of his class at West Point to have given his life to battle for his country.”

In September 1812, Gen. Dearborn gathered regiments from around the northeast to prepare for a major offensive in Canada and Hobart was involved in the taking of York on April 27, she said. In 1813, the forces moved against Fort George at the mouth of the Niagara River and on May 27, about 4,000 American soldiers went ashore to the west of the fort. British defenders fired at them. Hobart was the only American officer to die in the battle.

Dan Eccher sang “Goin’ Home” and the Kennebec County Veterans Honor Guard fired a gun salute. American Legion members from several posts recognized Hobart for his valor, Honor Guard Sargeant-at-arms Richard Braunfels spoke, Don Chase of the American Legion Post 40 of Winthrop, a U.S. Navy combat veteran who served in Vietnam, played taps, and Deb Couture of American Legion Post 181 of Litchfield and West Gardiner said a prayer.

“It’s an honor to be here to do this for him,” Chase said afterward.

St. Ann’s Burying Ground was quiet Sunday afternoon as sun filtered through maple and oak trees whose leaves moved in a gentle wind. Church archivist Jim Barnard said all veterans of the Revolutionary War and War of 1812 should be recognized and honored.

“Sadly, Hobart’s remains were never accounted for,” he said.

The original church was established as At. Ann’s Church in 1771 but burned and another was built in its place. The church outgrew the space and then the existing church was built adjacent to the others in 1820.

“It’s the oldest Episcopal Church in Maine and the first Gothic church in Maine,” Barnard said.

The bell tower on the church is being redone and the original Paul Revere bell will be returned to the tower, he said.

Couture, of Post 181, said she thinks it wonderful that Hobart is finally being recognized in his home town of Gardiner. She served with the Seabees as a medical planner for the Naval construction forces during the Iraqi and Kuwait wars.

Annie Cough, who lives just across the park from the church and is a member of the Kennebec Historical Society and active in genealogy efforts, placed a small American flag at Hobart’s memorial and ran her fingers softly over the top of the stone.

“Oh, it was very nice,” Cough said of Sunday’s event. “I coordinate putting flags out in Gardiner cemeteries, and I wanted to place one here.”
