Thijs, Thijs, you came to a people [of Paris], when they were doing well, now you must help them, when they are in distress. (translation from original Dutch, Fons Heijnsbroek, 2018)

Quote of Matthijs in his letter to Fidolin Becker, from Paris 1870-71; as cited by Haverkorn v. R. in Onze Kunst, 1918 - 2. p. 122 and beyond | Thijs registered with the National Guard, to defend the Paris' people against the Germans. Later Thijs told however he never loaded his rifle, he was only guarding. Later he got a lot of sympathy for pacifism.
