Pierre-Paul Pecquet du Bellet married Sarah Anne Elisabeth Moncure, born in Richmond in September 1826 and died in Paris in December 1914.

[7] Pierre-Paul Pecquet du Bellet, being a Confederate sympathizer living in Paris and fluent in the French language, immediately assumed the role of chief-representative of the Confederacy in France.

[12] In a June 1861 article for "Le Pays", du Bellet argued that the Confederates were Latins worthy of French aid, contrary to Northerners who were of Anglo-Saxon ancestry.

[13] Du Bellet was highly critical of Edwin de Leon, the Confederacy's unofficial propaganda agent in Europe, who disbursed important sums of money to influence journalists and newspapers to the Southern cause.

[15] Aside from writing articles in political newspapers, du Bellet also served the war effort by attempting to provide arms from France to the Confederacy.

[16] On 17 July 1861, he met in Paris with Rost and Caleb Huse, the Confederacy's procurement agent in Liverpool, regarding the possible acquisition of used French arms at an arsenal located in Vincennes.

[17] Napoleon III's secret police was soon tipped off that agents of the Confederacy, meeting in Paris on the rue du Helder, were seeking to acquire arms.

In this study, du Bellet argued that the Confederacy was heavily penalized by its amateurish agents abroad, including men such as Pierre Adolphe Rost, James Murray Mason, John Slidell, Samuel Barron, and Henry Hotze.

The abolitionist Moncure Daniel Conway, directly related to du Bellet's spouse, stated in his 1904 autobiography that du Bellet had told the Confederate government in Richmond that "as the war would certainly end slavery, even were the South victorious", emancipation should immediately be granted to gain international recognition of the Confederate States of America.

In 1869, he and other French citizens invested heavily in the Memphis, El Paso and Pacific Railway by purchasing bonds being sold in France by John C.

[21] When Frémont's project eventually collapsed, du Bellet and the other investors found themselves owning 640,000 acres of Texas land which had secured their bonds.
