March 1: Stp-US President Edward J. Phelps (Whig) offers a reward for the design of an orbital rocket with greater lift than any in use by the Great Powers, and an astronef able to cross the void to the other Earths swiftly, safely, and comfortably. This reversal of the usual Whig policy surprises many, but most of the smarter Stp-American politicians can see the way the wind is blowing. Stp-Earth's Russian Empire declares war on Nazi Germany. The fact that the Tsar's current favorite mistress is Jewish has nothing to do with that, of course. On Dp-Earth, a massive BRG rocket attack strikes at Peenemünde. The rockets that get through the crude-but-effective German missile defenses damage launch facilities and disrupt the next interplanetary fire mission. In the Dp-USA, Dr. Goddard's next 'probe', this time sponsored by the US Army, is launched, along with its attendant boosters. Hitler orders the alternative long-range launch facilities in German East Africa to be made ready ahead of schedule. On Inp-Earth, the Argentinian government points out that they are not at war with the Space Nazis, and thus the most moral act in regard to the Falkland Islands (which they call the Islas Malvinas) is to 'return' them to Argentina - several British tabloids make the claim that the reason Argentina isn't at war with the Nazis is that they're already ruled by them. Also on Infopunk Earth, the Papal sede vacante begins, Pope Benedict XVI having retired.
March 2: After some debate on both sides, Stp-France agrees to support Charles de Gaulle's Free French Forces, on the condition that the new Dp-French government will be a constitutional monarchy, with a strong monarch, under either the current head of the House of Bourbon on Dp-Earth, current head of the House of Orléans on Dp-Earth (either of whom would be Henri VI), or current head of the House of Bonaparte on Dp-Earth (Napoléon VI Louis), depending on which of the three Houses is the choice of the Estates of post-war Dp-France. Copies of the treaty are signed and witnessed on both Earths, and Stp-France declares war on Dp-Germany. The Papal States launch the first of four expeditions to the Romes of the other worlds, to 'help' the other Popes adjust to the 'correct' doctrines (those being the doctrines of Clement XV). This first mission is on its way to what some will later call Clockpunk Earth.
March 3: In orbit of Dp-Earth, the boosters are mated, all the math checks out, and the 'probe' (actually a delivery vehicle for military secrets FDR has elected to share with Inp-USA) is on its way. In Dp-China, Mao Tse-tung is executed by the Imperial Japanese Army. On Dp-Luna, several of the domed cities begin using masers mounted on the larger travel-spheres as transmitters, as these are less inconvenient to use than flashing the city lights, can still be used when the cities are in daylight, and are mobile, thus useful when the cities are facing away from Earth Prime. Instructions for a 'techbane' spell called
Hexus are posted to the internet. This is surprising mainly because it's a bit difficult for a Dresden-style spellcaster to use a computer (you generally need someone who uses a different style to shield your computer, or you need to be very, very calm while using it). The existence of this and similar spells is a large factor in the interest so many governments and corporations have in the development of 'anti-magical' or 'anti-psionic' defences.
March 4: On Stp-Earth, the Austro-Hungarian Empire, Holy Roman Empire (restored by treaty after the Franco-Prussian War, both to further humiliate the Prussians, and to make Germany less of a threat; if not for Prussia being a member, would be slightly smaller than OTL-Germany; Alexander IX did offer some Italian territories and a nice enclave in Rome, to go with the 'priviledge' of the Holy Roman Emperor being crowned by the Pope, but the Lutherans weren't having it), Papal States (only joining because Clement XV is an ardent monarchist - Divine Right of Kings, you see), Scandinavian Federation, and a few minor powers sign the Compact of Mainz, in which they pledge to join whichever side, Axis or Allies, will swear by oath and treaty to restore the legitimate governments (by which they mean,
and clearly state in the text, monarchies under the Habsburgs, Hohenzollerns, Wettins, Wittelsbachs, and so forth, with significant de facto and de jure power) of the German territories currently ruled by the Third Reich (analysts note that this would not actually require Hitler to step down, he'd just have to hand over some significant amount of real executive, legislative, and/or judicial power to them, as constitutional monarchs). While the Inp-USA and various other Earth Prime powers aren't pleased by this, most of the other Allies are fine with it (especially the Stp-British, French, and Russians, and the Dp-British and Free French; not all for the same reasons, of course), and begin drawing up just such a treaty. In Infopunk Iran, the 'mutant' rat problem reaches the point that ten sniper teams are sent to hunt them (
from Real Life, but weird enough to belong here; they're probably weirder and more threatening in this timeline, though).
March 5: A group of four glowing, spindle-shaped objects enter the Dieselpunk Earth-Moon system on a vector from the Mars of that world, pass through, and continue on separate courses for each of the other Earths, traveling at an average speed of around four light-seconds per hour. Maser flashes from Dp-Luna indicate that these are high-speed scout vessels of a design common to the more advanced Martian races: the Ice Warriors, the Changing Martians, and the Mysterons (each has variations, but the Lunarians aren't sure which is which), and that they travel by 'compressing and stretching the cosmic tapestry,' a process which allows very high apparent speeds and great maneouverability, and leaves them at rest relative to the largest mass near anything they collide with. Four light-seconds per hour appears to be their cruising speed, and the highest pseudovelocity the Lunarians have seen them use is nine light-seconds per hour, for about seven minutes. As each scout enters the 'portal' it's aiming for, it comes to an immediate dead stop relative to that Earth, starts and stops a few times at various speeds (and not the same ones in every dimension), makes a partial orbit around that Earth, and slowly accelerates to something other than normal cruising speed (to various degrees), on a course for the Mars of that timeline.
March 6: In Inp-Britain, a series of mysterious disappearances and other strange occurrences in and around Nether Wallop cause UNIT to first cordon off the village, and then evacuate it the next day. Advanced Idea Mechanics founded, in Dp-USA. Also on Dp-Earth, the Frank family is among the more than a hundred Jews smuggled out of Amsterdam to the UK on this date, by the reformed 'Ministry of Ungentlemanly Warfare' (Special Operations Executive). Young Anne is rather startled to learn that there are many millions of people on another planet who know her through a diary she hasn't even been given, yet. Speculation in the press that tight-beam masers are used to supply the Dp-Earth Allies with intelligence in a way the Germans cannot intercept are refuted when it's pointed out that at a range of about 26 light-seconds, the beam would be too wide to remain unnoticed (which is not
necessarily true).
March 7: The astronef carrying Stp-UK's ambassador to Inp-UK, along with various trade goods, scientists, and so forth, is launched from British Guiana, along with the first unmanned supply flight to the Stp-British space station. The crew, and some of the passengers, are veterans of both space and war. Stp-Russia announces plans to assemble a 'heavy' astronef at their space station, the first sections of which will be carried into orbit next month. Also announced is the launch of an embassy to Inp-Russia, next week. The empowerment of many scientists on Inp-Earth (along with the massive infusion of money for mundane research) now allows, among other breakthroughs, near-Hollywood levels of image enhancement (the magic is in the machines, and/or the users, not so much in the programmes, as yet). While it is not yet possible to distinguish individual humans as more than a few pixels at thirteen light seconds out, and not at all at twenty-six, such a high resolution is now plausible in the near future, rather than a pipe-dream. Of course, the reliability and accuracy of these enhancements is still questionable, but experiments so far have been very promising.
March 8: Around 3am GMT, reporters and other curious folk lurking near the perimeter outside Nether Wallop hear shouting, gunfire and other explosions, and 'electric noises', as well as seeing strange lights. First confirmed Drop-Bear attack, in Inp-Australia. In Dp-Sunnydale, California, having been tipped off by observers on Inp-Earth who were also BtVS fans, the FBI, assisted by Dr. Fate, arrests Mayor Richard Wilkins II (who as it turns out, is also Mayor Richard Wilkins I), for electoral fraud, negligence in office, and general corruption, among other things.
