This cover was sent from the ambulant post office in the Belgian Army (Postes Militaires - Legerposterij) on 22 June 1918 and arrived at its destination in The Hague (The Netherlands) on 14 July 1918.
It is worth comparing this cover with another censored cover from the military post to the same person in The Hague in 1918, probably a husband writing to his wife.
