March was a month.
Between 1 March and 6 March 1941, the Hartung Project was forwarded by the Luftwaffe zbV following the death of Emil Hartung. Resulting in tragedies like the Granville raid, the Seventh Doctor and Jason Kane both worked to thwart the Project, as it had resulted from them letting slip anachronistic information about radar technology in 1936. (PROSE: Just War, AUDIO: Just War) Bernice Summerfield experienced both versions of events with the Doctor and with Jason. (PROSE: Paydirt, Dear Friend)
One Saturday in 1943, the Third Doctor arrived in Los Alamos in New Mexico and made discrete changed to Niels Bohr's notes, ensuring that the Manhattan Project would be successful. (PROSE: Come Friendly Bombs...)
In 1944, both Britain and Germany decrypted a Wyrrester code holding instruction on how to build a transmat device. The Germans developed Die Glocke but failed to make it work. The British tested the Bell on 21 March but it was destroyed by the Luftwaffe after it paved the way for a Wyrrester attack. (PROSE: The Crawling Terror)
One Tuesday night in March 2007 was "when it all changed" for LINDA. Victor Kennedy, also known as the Abzorbaloff, discovered LINDA and quickly took command of the group to help him find the Doctor so he could absorb the Time Lord and gain access to the TARDIS. (TV: Love & Monsters) He also assimilated a secretary into his body. (WC: Tardisode 10)
In 2197, the Sixth Doctor and Evelyn Smythe returned to the Valiant in the TARDIS from their trip to 7 September 1952. Since they departed on 16 January, thousands of the crew had fallen victim to Hayman, heard an old bell and walked through an even more ancient, impossible door in open space to their deaths. The Doctor covered the entrance to the door, and dematerialised, bringing the portal door with it. Meanwhile, Captain Tanya Oswin of the Valiant ordered nuclear missiles to be launched at the location where the door had been. The remaining crew evacuated, but companion Evelyn Smythe stayed behind out of faith for her friend. The Doctor, after visiting "Time's End" with Hayman, changed the coordinates of his ship so that the missiles would destroy it circa 50,000,000,000 BC. The Doctor and Evelyn, having saved humanity from one of its predecessors, departed. (AUDIO: The Nowhere Place)
The Second Time Front reached its climax in March 1970. On Germania I, one of the Known Worlds on which Nazi Germany reached its full potential, the Roman armies of the Empire of Empires entered Berlin on 3 March and General Wilding agreed to surrender on 10 March. (PROSE: Warlords of Utopia)
