Learn how the Allies uncover the Nazi's secret V1 project and what Col Wachtel does to gain the upper hand. Col Wachtel's regiments are posted to launch sites in Northern France, but the Luftwaffe have lost control of the skies. The distinctive shape of the site buildings makes them stand out in Allies reconnaissance photos. When they also get a shot of a V1 on a ramp, they start a bombing campaign on the French sites. Col Wachtel abandons all the sites and both he and his regiments move undercover. New, small launch sites are designed that can be built at the last minute.
