The above diagram has been created using several sources, see below.

Notes:

Positions of tanks within sections are not given in the sources but are educated guesses based on the order they appear in the list of 7 and 8 companies in the Berkshires War Diary. The first tank listed in each section is assumed to be the advanced guard tank, the seconds the left tank and the third the right tank. This is the order used in H Battalions list. (W5Berk p132f)

The 9 Essex infantry formations are not know, the above is based on that used by the 5 Berkshires.
