Some information I came across doing my research for the British hold Crete thread. The information is from page 269 of Volume 2 of the Mediterranean and Middle East.
The reinforcements sent in operations Substance and Style increased to the combat strength of the garrison to over 22,000 at the beginning of August 1941.
The number of infantry battalions had been increased from 10 (7 British and 3 Maltese) at the end of June 1941 to 13 (10 British and 3 Maltese).
There were also:
112 heavy anti-aircraft guns in 14 batteries (8 RA and 6 RMA) so the requirement set in 1939 had been filled
118 light anti-aircraft guns in 11 batteries (7 RA and 4 RMA) so the requirement set in 1939 had been exceeded
104 light, field and medium artillery pieces for use in beach defence and mobile operations
The stocks of most items of military stores were sufficient for eight months, and of some for as much as fifteen.
The original 'target' figure for fighter squadrons had been fixed at four, but by January 1941 there was only one. Now, at the beginning of August 1941, there were fifteen Hurricane Is and sixty Hurricane IIs serviceable.
