Louis Victor Plessier (19 May 1856 – 27 August 1914) was a French general. Joining the army in 1874 Plessier fought in the Sino-French War and in Algeria. As a general in the First World War he led his brigade during the Battle of Mulhouse where he was wounded by German fire. Plessier, hit in three places in his spine, succumbed to his wounds eight days later in hospital. He is sometimes regarded as the first French officer to be killed during the war: although four other generals died before he did, his mortal wound was the first.
