Cablegram 78 LONDON, 30 March 1939, 8.42 p.m.
At meeting this evening the Secretary of State for Dominion Affairs  informed the High Commissioners of the decision being conveyed in Dominions Office telegram 126 to you tonight.  It is hoped that the French and Polish replies will be received in time to enable the declaration to be made tomorrow Friday. In that event it will be made in answer to private notice question which will be put in the House tomorrow. Its terms have not yet been finally settled but it will be down the lines set out in telegram.
There have been reports of German troop movements and military activity but they are not confirmed from official sources. There has also been a report that some German operation is to be ready to start at the end of this month but there is no official observation which confirms this report. United Kingdom Government reached the conclusion this morning in view of possibilities in the next few days that Germany must be left in no doubt as to the attitude of Great Britain in the event of attack upon Poland.
