CORPS HEAVY ARTILLERY.
A. Plus 7 hrs. 40mins. – 8.40 mins. Search area on 8th and 18th Divisional front
between the protective barrage line and the first line of posts to be established, with 36 heavy guns and howrs., and paying particular attention to all houses and woods in area. Rate of fire ½ round per gun per minute.
B. Plus 7.40 – 8.40. Four 9.2” Hows. And six 60 pdrs. Search trenches in
BROODSEINDE – MOLENAARELSHOEK from J.4.b.6.0. – D.28.b.9.3.
Rate of fire ½ rounds per gun per minute.
C. P8.40 – 9.5. Search area on 8th and 18th Divisional fronts with every
available gun and howitzer, between the 1st and 2nd line of posts to be established, but not to shoot within 500 yards of the Western line after 9 hours and to pay particular attention to the trench system from J.4.b.4.0. to the railway at D.22.b. west of BROODSEINDE – NOORDEMHOEK RIDGE and to the Ridge itself. Rate of fire 1 round per gun per minute till 8 hrs. 50 and then ½ rate.
From 9 hrs. 5 to 9 hrs. 30 the protective barrage covering the 8th and 18th Divisions will be formed by 52 heavy and medium guns and howitzers and all the F.A. of 8th and 30th Divisional Artillery Group which can reach, 500 yards in front of the line of posts.
The protective barrage is shewn in ORANGE on Map.
From 9 hours 30 minutes onwards this line will remain the S.O.S. line till news is received of the exact positions where posts have been established.
From the above it should be noted –
(1). That the protective barrage 500 yards in front of GREEN LINE will require to be clearly watched to see when it lifts. There will be so much shooting further to the west that unless watched it might lift unnoticed.
(2). There will be no creeping barrage in front of the patrols.
(3). The quicker patrols make ground the more advantage will they be able to take of the confusion created by the area shooting which is taking place east of them.
