Early reports

By the summer of 1941 Home Army intelligence began receiving reports from its field units regarding some kind of secret tests being carried out by the Germans on the island of Usedom

A special "Bureau" was formed within intelligence group "Lombard", charged with espionage inside the 3rd Reich and the Polish areas incorporated into it after 1939, to investigate the matter and to coordinate future actions.

 (the first launch from there was on November 5, 1943), the AK had a unique opportunity to gather more information and to intercept parts of test rockets (most of which did not explode).
The AK quickly located the new testing ground at Blizna thanks to reports from local farmers and AK field units, who managed to obtain on their own pieces of the fired rockets, by arriving on the scene before German patrols. In late 1943 in cooperation with British intelligence, a plan was formed to make an attempt to capture a whole unexploded V-2 rocket and transport it to Britain.

At the time, the opinion within British intelligence was divided. One group tended to believe the AK accounts and reports, while another was highly sceptical and argued that it was impossible to launch a rocket of the size reported by the AK using any known fuel.
Then in early March 1944, British Intelligence Headquarters received a report of a Polish Underground worker (code name "Makary") who had crawled up to the Blizna

The Polish intelligence also informed the British about usage of liquid oxygen in a radio report from June 12, 1944. Some experts within both British and Polish intelligence communities quickly realized that learning the nature of the fuel utilized by the rockets was crucial. Hence, the need to obtain a working example.

From April 1944, numerous test rockets were falling near Sarnaki village, in the vicinity of the Bug River

According to some reports, around May 20, 1944, a relatively undamaged V-2 rocket fell on the swampy bank of the Bug near Sarnaki and local Poles managed to hide it before German arrival. Subsequently, the rocket was dismantled and smuggled across Poland. Operation Most III

Impact on the course of the war

While the early knowledge on a rocket by AK was quite a feat in pure intelligence terms, it did not necessarily translate into significant results on the ground. On the other hand, the AK did alert the British as to the dangers posed by the rockets which led them to allocate more resources to bombing production and launching sites and thus lessened the eventual devastation caused by them. Also, the Operation Hydra
