Otto Mandrup Tennison was born in Copenhagen, Denmark on December 8, 1834. He attended Heidelberg University in Germany as an engineering student and graduated at the age of 20. He then moved to Richmond, Virginia and became a surveyor. He then traveled to Kansas Territory where he surveyed an area which became the city of Leavenworth in 1854. It was the first incorporated city in Kansas.

On May 31, 1861, Tennison enlisted as a Union Sergeant in the First Regiment Kansas Infantry. He was erroneously reported killed in action in August, 1861 at the Battle of Wilson’s Creek (also known as the Battle of Oak Hills), near Springfield, Missouri. It was the first major battle of the Western Theater of the American Civil War and sometimes called the “Bull Run of the West.” It was a Confederate victory.

He was later appointed 1st Lieutenant, then Captain (November, 1961), then Lieutenant Colonel in August, 1862. He served under Major General Ulysses S. Grant. Tennison was the Commander of the 1st Kansas Infantry, organized at Camp Lincoln, near Leavenworth, Kansas.

In May, 1863, Tennison made a conscious decision not to support the Union cause and resigned his commission. He was ordered to report to Camp Alton in Illinois to face court-martial, but escaped and took a horse to the Confederate camp of General Edmund Kirby Smith (1824-1893) in Kentucky.

Tennison, who wanted to join the Confederate Army, was, instead, taken as prisoner and held captive for 16 months. The Confederates thought Tennison was a Union spy and he was sentenced to hang. But at the last minute, his sentence was reprieved and he was sent to Shreveport, Louisiana. Convinced he was not a Union spy, the Confederate army gave him the rank of Captain in June, 1863. He was later wounded at the Battle of Pleasant Hill near Pleasant Hill, Louisiana on April 9, 1864.

He became a drill master throughout the rest of the Civil War. He left the Confederate army in June, 1865 and moved to New Orleans. He worked as a civilian in the commissary.

In 1873, Captain Tennison commanded a company in New Orleans and resorted to an armed insurrection against the New Orleans Reconstruction government.

Over the years, Tennison was involved in other military commands and participated in the Louisiana Militia, the Continental Guards, the German Battalion, the Orleans Light Infantry, and the Louisiana National Guard, in which his unit was known as the “Tennison Rifles.” The unit had 75 members.

In the 1880, Tennison was a charter member of the New Orleans Chess, Checker, and Whist Club.

Throughout the 1880s and 1890s, he served as a reporter for the Republican newspaper and was also involved as a court reporter at the House of Representatives of the State of Louisiana.

On July 26, 1891, he published analysis on the opening 1.Nf3 d5 2.e4 (which can also be reached by 1.e4 d5 2.Nf3) , which appeared in the New Orleans Times-Democrat. He called the opening the “Black Rook’s Gambit.” It was later called the Tennison Gambit or the Abonyi Gambit, named after Istvan Abonyi (1886-1942), a chess master from Hungary who first analyzed and played 1.Nf3 d5 2.e4 in 1912.

On June 10, 1909, at the age of 74, he died in the Confederate Soldiers’ Home in New Orleans.

<Capt. Mackenzie Contests a Tournament With Fourteen Players, Winning Eleven Games, Losing One and Drawing Two>

Last night, at the elegant rooms of the Chess, Checkers and Whist Club, Capt. G. H. Mackenzie, the celebrated chessplayer, played a peripatetic tournament against fourteen gentlemen as follows, with the several openings with which the games were commenced. Each player had his board, and the champion moved around the room in turn.


The gallant captain charged his fourteen opponents in vigorous style, pausing seldom more than a moment at any table until most of the contestants had succumbed to his tactics. At the end of an hour but six players were holding out against the champion. Tennison, by his skillful playing, forced the captain to strike his colors.
