Behind the churchwardens, it is really the bishop who demands the demolition of the church. As a matter of fact, on April 25, 1805, by a decree given at the Stapinigi Palace, the Emperor orders that the prefect of the department of the Aisne, at the instance of the Bishop of Soissons, shall put at his disposal the church of Saint-Jean-des-Vignes, "in order that the materials coming from the church may be used in the repair of the cathedral": the inhabitants of Soissons must merely, in exchange for this concession, consolidate the walls of the other parts of the abbey which have been granted to the Administration of Powder and Saltpeter.
Mgr. Leblanc de Beaulieu receives his decree. Meanwhile the inhabitants of Soissons are alarmed at this project of demolition, protest against the plan of the prelate and take their grievances to the prefect. It is often assumed that before the advent of romanticism no one in France cared for the monuments of the Middle Ages. Now, as early as 1805, the news that the church of Saint-Jean-des-Vignes is about to be destroyed excites the indignation of the people of Soissons. The archaeologists make ready for battle. The prefect writes to the bishop (June 26, 1805): "Monsieur, I am receiving a great number of complaints against the approaching demolition of the church of Saint-Jean: the inhabitants of Soissons appear to be extremely attached to this edifice, which they regard as a precious monument of the arts. I have the honor to forward to you a copy of a historical summary which has been forwarded to me. As it belongs to you, Monsieur, to decide the fate of this church, which is at your disposal, I can only confide in what your good sense and your enlightened love for the arts will suggest to you."
His "enlightened love for the arts" does not in the least inspire the bishop with a desire to save the church; but the complaints of his flock embarrass him, and he explains to the prefect that he himself cannot proceed in a regular manner, that it is unsuitable that a bishop should have "personal connection with the demolition of a church." And, for four years, matters remain at this stage.
Finally, in 1807, disdaining the protests and triumphing over his own scruples, the bishop awards the glass and the ironwork to a certain Archin. In 1809 he empowers his notary to treat in his name with the contractors for demolition. All that he accords to the inhabitants of Soissons is the preservation of the façade.
The bargain is concluded between "Antoine Isidore Petit de Reimpré, imperial notary, domiciled at Soissons, in the name and endowed with the powers of Mgr. Jean Claude Leblanc-Beaulieu, Bishop of Soissons and Laon, baron of the Empire and member of the Legion of Honor, of the first part; and Leonard Wallot, building contractor, and Pierre-Joseph Delacroix père, carpenter...." By the terms of the agreement, the two towers and the portals must remain intact, and the contractors are even obliged to do certain work of consolidation. But nothing will remain of the nave and the choir of the church: "All the parts to be demolished shall be demolished down to and including the foundations. The rubbish caused by the demolition shall at first be thrown into the vaults of the church; consequently the ceilings of the aforesaid vaults shall be demolished, the ground shall be perfectly leveled and the surplus of the rubbish shall be transported into the fields." This is not all. The bishop reserves for his own share a hundred and sixty cubic meters of ashlar! The price of the sale was fixed at three thousand francs.
For six hundred dollars, they leveled to the ground a marvelous Gothic edifice, the largest church of the diocese except the cathedral; the choir was composed, as a matter of fact, of two bays, the transept likewise of two bays, and the nave of five; it was sixty meters long and twenty-six high. It is an excellent custom to carve upon the monuments the names of those who have built and repaired them. It would not be ill if upon the ruins of Saint-Jean-des-Vignes an inscription should recall the absurd demolition and the name of its author, Mgr. Leblanc de Beaulieu.
In 1821 the demolition was not yet complete, for Wallot found some difficulty in selling his ashlar. It is said that several houses of Soissons were built with the stone of Saint-Jean-des-Vignes.
