Morning: Lichnowsky has a message from Bethmann saying Russia might be calling up reserves without declaring a mobilisation. “We therefore request Sir Edward Grey to use his influence at St Petersburg”. Lichnowsky writes a note for Grey saying if Russia calls up reserves Germany will mobilise. “My Government … instructs me to request you to use your influence in St. Petersburg”.
He also communicates Berlin’s acceptance of Britain’s first mediation proposal “My government accepts your suggested mediation à quatre”. (This mediation suggestion has now been overtaken by Nicolson’s four-power ambassadors’ conference idea.)
