=============================================================
(8) The above alterations will affect Appendix “C” slightly, Group Commanders should consequently consider these slight alterations:-
“V”. Concentration of Right Group should now be considered under “X” day expenditure, whereas the expenditure allowed for concentration on “X” day may now be cancelled.
An additional expenditure of 15 rounds of 18-pr and 10 rounds of 4.5” per gun should be added to “W”, “X” and “Y” days for intense bombardment in support of discharge of gas.
