I think it was more a case of, "Oh, shit!!!! Tigers!!! Chaaaaarge and get amongst 'em, boys!!"
The text in one piece about the event goes, "At least one case is known of vehicle commanders using the vehicle's fast speed to jump large gaps. In the Netherlands, a troop of three Cromwells was able to leap a 20 ft (6.1 m) wide canal when surprised by enemy forces." Trying to find the full story again but Google's letting me down at the moment.
Another report refers to Cromwells regularly solving the problem of hedgerows in Normandy when ambushed from them by putting the hammer down and leaping over them, much to the surprise and horror of any Germans dug in behind or even in them.
Apparently, the record was 31ft by a demonstration troop at Bovington, using a concrete ramp.
Must have buggered the suspension no end.
