Date: March 22, 2024 - Lecture #2 of an 8-part series
Topic: Overview of Early Anglo-Saxon History
The Anglo-Saxons first appeared on the periphery of the British Isles at the time of the Roman withdrawal. Originally appearing as small marauding hit-and-run bands they would, over 400 years, conquer and displace the Celtic kingdoms. They eventually coalesced into seven regional kingdoms and reunified what they called England. Weakened by Nordic incursions they would succumb to two massive simultaneous invasions. This is their story.

Presentation: The zoom link is below. This concludes our five-part lecture series on the Pacific Campaign.
https://us02web.zoom.us/j/81709521405

The Pearl Harbor Raid was a catastrophic event for the USN in the Pacific and the country as a whole. It was a calculated high-risk strategy that Japan hoped could trigger a negotiated end to hostilities avoiding the need for a Long War scenario.
Failing this, it was hoped to delay a meaningful American response for 12-18 months. This period would allow Japan to extensively prepare and uninterruptedly exploit the oil and mineral resources of its conquered territories. Meticulously planned and practiced for, it failed in several key regards. It did, however, undeniably illustrate a new naval strategy, the use of multiple aircraft carriers operating
together. Unfortunately for them, it was one the USN later adopted to stunning effect…

The USN fought the only successful submarine anti-commerce campaign in the course of World War II. From modest origins and obsolescent boats plagued by horrendous torpedo malfunctions, it emerged to cripple the third largest merchant marine
service in the world. As the war grew in scope and numbers, the Silent Service, not only crippled the Imperial Japan cargo fleet it also branched out into many other vital services Chief among these was pilot search and rescue, a majority of the time under direct
enemy fire. In this role, they rescued over 500 downed aircrews. The lecture will trace one of the most unique forces in U.S. military history.
