The attached diagrams are forwarded for your information.

They indicate the results of the two Tests of forwarding barrage on line “H” carried out with aeroplane observation.

The 15 barrage batteries fired salvoes of 4 rounds each in succession from the right at 4 minutes intervals.

The attached diagrams were in possession of the aeroplane observer, who marked four dots for the four rounds of each battery and enclosed them in a circle.

On completion of the observation the Pilot flew over Div H.Q. & dropped message containing diagram. The latter was received within 10 minutes of last round being fired, and a tracing forwarded to each Group. – The barrage appears satisfactory.

Could you please return attached diagrams.

Dear Colonel,

 

We have just received information that the operations for Z day have been postponed for 48 hours.

 

No Programme of Bombardment or official orders have been received yet, until such orders are received the General wishes Wire cutting to be continued where required taking advantage of the extra two days to profit by good light – Ammunition should not be expended unnecessarily but where wire remains it should be engaged – He also wants 18 prs to continue preventing the repair of wire.

As soon as possible a programme for the extra two days will be sent out.

Yours Sincerely A.F. Brooke
