I found another link on the 3rd Hussars. Which states:
"The remaining and reconstituted 3rd Hussars were re-equipped with Crusader, Sherman and Grant Tanks ready for the Battle ahead. In the first phase of El Alamein the regiment helped break through Rommel's Defences but in the second phase it was given the crucial task of forcing a gap through the remaining defences to enable the armoured reserves to break through. The "Moodkee Wallahs" succeeded and Alamein was won, at a cost of 21 Officer casualties and 98 other rank casualties whilst of their 51 Tanks, 47 were destroyed in the battle. So decimated was the Regiment that it was unable to join the pursuit. General Freyburgh granted the 3rd Hussars the Honour of wearing the "Fern Leaf" on their vehicles because of their participation with the New Zealand Division during the Battle."

There is no references to Cromwells anywhere.
