By September 1861, Senac had been appointed paymaster of the CSS Mississippi and CSS Louisiana, both being built in shipyards outside New Orleans.
He was living with his family in New Orleans when the city fell to Union forces on April 26, 1862.
 The family had secured access to flee New Orleans and were living with other members of their family in Covington, Georgia.
 On September 15, 1862, Senac was summoned to Richmond, Virginia, in front of a Congressional Committee to explain the reasons for the loss of the two Confederate ironclads.
 Having received new instructions to operate as a C.S. Navy agent in Europe, Senac and his family left Wilmington, North Carolina, in June of 1863.
 Having reached London, the family ultimately settled in Paris as Senac traveled to England and around Europe trying to secure clothing, shoes, and weapons for the Confederacy.
 His ultimate goal had been to supervise and pay for the construction of the CSS Sphinx and the CSS Cheops.
 These ironclads had been given Egyptian names in the hope that U.S. spies would believe the ironclads were destined for the Khedive of Egypt.
On February 28, 1865, as Confederate agents in Europe were slowly preparing to make their way back to the Confederacy, Senac received orders from Richmond to stay in Paris.
In the summer of 1865 he moved with his family to Wiesbaden, Germany, and wrote his nephew that he would be traveling to South America to start a new life there.
Senac died a few months later on January 27, 1866, in Wiesbaden and is buried there.

His wife and daughter Ruby left Wiesbaden for Paris where Ruby married the Confederate propagandist Henry Hotze in Paris in 1867.
 Following Hotze's death in 1887, Ruby survived her husband by several decades.
She continued to live in England and then moved to Washington, D.C., with her mother Marie Louise who died on October 2, 1898.
Ruby was employed in the U.S. Census Office on July 1, 1890 and then became a clerk in the Signal Corps.
She was transferred to the U.S. Weather Bureau in 1891.
She died on January 3, 1929, in Washington, D.C., at the age of 84.
She is buried at Mount Olivet Cemetery.
