The White Eagle of Poland by E.F. Benson

Germany seems to have realised from the first that the management of the occupied territory of the Kingdom of Poland would present difficulties, and, apart from its systematic starvation, necessitated by the needs of her armies, and her desire for industrial emigration into Germany, she adopted a wiser policy than she did, for instance, in Belgium. Warsaw was taken on August 5, 1915, and schools were reopened there by August 25th, and both in primary and secondary classes Germany allowed Polish to be taught. German and Polish in fact were compulsory languages in schools, and German was taught by Poles. Russian, however, was completely prohibited, and no books or papers other than those that had passed a German censorship were allowed to be introduced into the territory at all. Similarly as an anti-Russian measure she permitted the Byzantine ritual for Greek Catholics, which Russia had prohibited.

Now Germany had barred the teaching of Polish in schools in the Duchy of Posen and Prussian Poland, but then she had definitely annexed them and incorporated them into the German Empire, and any attempt at conciliation there was mere weakness. But she was still doubtful whether this fresh conquest was ripe for a similar coercion, and in the interval she tried with an amazingly small degree of success to establish friendly relations with the inhabitants.
