I found UNDAUNTED VALOR: LAM SON 719 by Matt Jackson was captivating from the beginning until the end. I was in the 101st Airborne as a grunt during the 45-day campaign in 1971 and remember that our unit was primarily used in firebase defense as helicopters were scarce at the time as most in-country were used for this foray into Laos.
The story was told from the viewpoint of Lt. Cory of the 1st Cav. from An Khe. His crew and two others from the unit were sent north with their ships to support the South Vietnamese attempt to sever the Ho Chi Minh Trail in Laos. Each mission was dangerous and nerve-wreaking, ships sustained damage and/or crashed daily while having to land or pick up soldiers through a non-stop hail of gunfire. I did find the daily briefings redundant, and after the 3rd briefing, I began to skim over them.
In the story, Lt. Cory shared his experiences during the flights he participated in. However, the story on the ground was never told. Readers learned of troop evacuations necessary because firebases were on the verge of being overrun, Yet nothing was told about the ground battle or if there were survivors. As a result, the story seemed one-sided.
I heard how the invasion to sever the Ho Chi Minh Trail failed in Laos, and now I understand why that happened. It's unfortunate that so many aircraft, pilots and helicopter crews lost their lives or were wounded during the operation which South Vietnamese soldiers primarily fought on the ground.
All-in-all, I'd recommend this book to anyone interested in this particular operation or in understanding the role of helicopter pilots during the Vietnam War.
