Operation Biting
The 1942 Parachute Assault to Capture Hitler's Radar
Max Hastings 2024 | West Slope 940.5412 HASTINGS
This is a book about people and relationships and inferred attitudes. Not about geography and timing and technology, the aspects that interest me most. The Appendices are the most interesting:
p261 Appendix I: Major John Frost's Orders for Operation Biting February 1942
- p271 Appendix II: Order of Battle for C Company 2nd Parachute Battalion 28 February 1942
- 3 groups, 11 teams, dropped 0014 to 0039
- equipment: 5 #38 wireless sets, 2 #18 wireless sets, 2 mine detectors, 5 antitank mines, 3 Trolleys, 2 Eureka beacons
