Edmond Alphonse Léon Buat (17 September 1868[1] – 30 December 1923[2]) was a general in the French Army, who served as Chief of the Army Staff from 25 January 1920 until his death.

In World War I, Buat commanded first the 121st Infantry division and then the 2nd Army Corps.

When asked by Alexandre Millerand whether the French Army had the capacity to occupy the Ruhr he replied that this would only be possible by mobilising the reserves.

On 10 July 1927 Petain, Alexandre Millerand and Ragueneau attended the inauguration of a monument to Buat in Nantes.

[4] He wrote several books on military history specialising in artillery tactics: His journal, Journal du général Edmond Buat 1914-1923 was published posthumously by the French Ministry of Defense in 2015.
