By the way, a 100 MPG auto is feasible. The record was 149.95 MPG with a 1947 Studebaker in 1949 which was increased to 376.59 MPG with a 1959 Opel in 1973 and the current world's record is 12,665 mpg (US gallon) although not set with an automobile that the average man would want to drive. -- Cheers, John B. |

I guess the Italians followed the Polish bad example. I dunno about the hand grenades. Tossing grenades in the middle of a densely packed cavalry charge, on open ground, is going to produce collateral damage. Until I just read the following pages, https://en.wikipedia.org/wiki/Charge_at_Krojanty http://www.polamjournal.com/Library/APHistory/Cavalry_Myth/cavalry_myth.html I had thought that the Polish cavalry really did try to attack German tanks at the start of WWII.

Apparently, this was not true. Interesting item on that page regarding autumn 1939: "Each single-turret version of these Polish 7TP tanks carried a 37mm main gun and up to 17mm of armor plate. They were superior in both armor and armament to most of the invading German tanks, and they were the world’s first diesel powered tanks to see action. " Yet the richly detailed masterwork _Nomonhon_ [1] says that at the start of skirmishes in 1938 there were mixed diesel and gasoline tanks and armored cars on both sides but the gasoline vehicles proved so fatal to their crews that at the end, summer 1939, mostly diesel were fielded. As regards 'action', Zhukov rolled up the Kwantung Army like a used carpet with 75% casualty rate (45,000 of the 60,000-man force) [1] https://www.alibris.com/Nomonhan-Jap...995?matches=37 -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

"The charge was successful, the German infantry unit was dispersed, and the Poles occupied the clearing. However, German armored reconnaissance vehicles appeared from the forest road, the Polish units came under heavy machine gun fire and gallop for cover behind a nearby hillock. "About a third of the Polish force was dead or wounded. On the other hand, the German advance was halted long enough to allow the withdrawal of Polish 1st Rifle battalion and National Defence battalion Czersk from the nearby battle of Chojnice." In essence, the Calvary charge was a success. -- Cheers, John B. |
