Gregory VII replied with a rough letter, dated 8 December 1075, in which, among other charges, he accused the German king of breaching his word and with his continued support of excommunicated councilors.
Grgur VII. odgovorio je oštrim pismom datiranim 8. prosinca 1075., u kojem je, uz ostalo, optužio Henrika da je prekršio svoju riječ, te da i dalje potpomaže izopćene vijećnike.
