Du MARTROY Marshal Lefebvre's staff officer. Battle of Wagram Autograph letter addressed to his father Mr. de Martroy at Château de Balagny, Département de l'Oise. Linz, July 8, 1809; 2 pages in-4° with address and postmarks. Small perforations on left side. "[...] great and good news that a page of his Majesty has just transmitted to the Duke of Danzig and that the latter was good enough to have me tell him almost immediately: a great battle has taken place under the walls of Vienna.... The battle lasted more than two days and two nights, I think even three days. The enemy has been driven from all his positions, his left wing and center are turned and in full rout, everything is fleeing before our Emperor, who is in good health thanks be to God; we have taken an enormous quantity of prisoners to such an extent that the number is still unknown, here are the results so far known: 100 pieces of cannon, 10 flags are in our power, 20 enemy generals have been killed, the Archdukes Louis and Charles have both been wounded, it is said that the last is mortally wounded. Our army is pursuing its successes, which will be immense, given that it seems that almost all the corps are cut off and divided... I have just received further news that we have 30,000 prisoners, but the number will surely have risen by the time I write. It wasn't the Marshal who sent me the news, he's been away for 3 days." Enclosed: a death certificate for Jean-Baptiste Rouge, who died in Vienna, Austria, on July 8, 1809. Done in Paris on December 24, 1810.
