After leaving the beaches during the Battle of Normandy, the Americans confronted the Germans on the so-called "bocage", or pastoral land. This included large "hedgerows," that made it excellent defensive terrain for the Germans.
During the campaign, some American soldiers came up with a brilliant idea for what later was called the "Rhino tank". That was a tank to which metal pieces or "prongs" were attached to the front. This could be used to knock down the hedgerows, and help flush out the defending Germans.
Are there any records of what improvements (e.g. speed in miles per day, lower rates of casualties) the Allies enjoyed after, compared to before, the introduction of the Rhino tanks? This question would apply only for the time the Americans (and British and Canadians) were fighting in bocage/hedgerow territory.
