Kilmaine is historically honored at the Arc de Triomphe in Paris, where his name can be seen on the inside triumphal arch, on the Northern pillar, Column 05.
  Underneath the Arc is the Tomb of the Unknown Soldier (World War I).


In the memoirs of Captain Landrieux, his aide-de-camp, Kilmaine is described as
"the only officer in whom Napoleon ever placed complete and utter confidence."

 A generous man, he frequently supplemented out of his own private means the rations of his men, who with difficulty were prevented from deserting and more importantly kept alive.

In the Memoirs published by General Charles Tristan, Marquis de Montholon, he wrote of Jennings,
"Brave and noble Kilmaine, being an excellent cavalry officer, had coolness and foresight, he was well fitted to command a corps of observation, detached upon those arduous or delicate commissions which require spirit, discernment, and sound judgment.
He rendered important services to the army, of which he was one of the principal generals notwithstanding the delicacy of his health.
He had a great knowledge of the Austrian troops, familiar with their tactiques, he did not allow himself to be imposed upon by those rumors which they were in the habit of spreading in the rear of an army, nor to be dismayed by those heads of columns which they were wont to display in every direction, to deceive as to the real strength of their forces.
His political opinions were brilliantly moderate."

Wolfe Tone wrote of Kilmaine in his private journal.
 One of his diary entries read, 
 "Clarke then said there were some Irish officers yet remaining in France, who might go, and he mentioned Jennings, who used to call himself Baron de Kilmaine, God knows why.
  I answered, that in Ireland we had no great confidence in the officers of the old Irish Brigade, so many of them had either deserted, or betrayed the French cause, that, as to Jennings, he had had the unfortunate misfortune to command after Custine, and had been obliged to break up the famous "Camp de Caesar", that, though this might probably have been no fault of his, it had made an impression, and, as he was at any rate not a fortunate general but a typical Irish soldier of fortune, I thought it would maybe better to have a Frenchman."

There is a personal portrait of General Kilmaine in the 'Hotel de Ville' (City Hall) at Tonnay-Charente, where his father Dr. Theobald Jennings practiced as a physician.

A monument was erected in his memory in Tonnay-Charente in the 19th century.

Rue du Général Kilmaine, a street in Tonnay-Charente, was named in his honor in the 19th century.
