Here are two photos from my files showing a log carpet layer developed for Dieppe by a Canadian Engineer, Maj B Sucharov MBE. The photos were taken in May 1942, on the Isle of Wight.
Sucharov was awarded the MBE for his work. The citation reads:
SUCHAROV, Bert, Major - Member, Order of the British Empire - Engineers (1st Battalion, Royal Canadian Engineers) - awarded as per Canada Gazette dated 1 January 1943 and CARO/2983 dated 4 January 1943; confirmed in CARO/3580 dated 2 September 1943.
The initiative, drive and zeal of this officer have been outstanding since he landed in England in February 1940. He displayed great leadership and tireless energy in the engineer preparations for the Dieppe operations and experimented with new design of high explosives for offensive demolitions. He personally designed and produced the official attachments which enabled the tanks to overcome the shingle beaches and surmount the sea wall at Dieppe and during operations displayed the highest qualities of courage and resolution under heavy fire.
Of interest is that Sucharov was not just a back-room boffin but actually accompanied his invention into battle.
