It has now been largely confirmed that a lost branch of the Nile River, called the Ahramat Branch, flowed very close to where the ancient Egyptian pyramids were built. This would imply the river was seen as much more symbolically significant to the pyramids than has been previously assumed, although building materials were also transported by boat.

6th of June is the 80th anniversary of D-Day, 1944. This important invasion of Normandy by Allied troops opened a second front against Nazi Germany, immensely hastening the collapse of the German armed forces. It took years of preparation and collaboration.

Linked is the UK and French page for commemorations, but the event is obviously an international one. For most veterans it will be their last event.

What follows will be real time updates of the day as I did for a previous anniversary.

About midnight: bombing of Normandy begins.
There are rumours and hints within German military intelligence that an invasion is about to begin. Notably, a poem read over the radio a few hours earlier sparks suspicions. It is indeed a coded message to the French resistance to begin sabotage operations. But already confused by conflicting and often wrong hints, the German military takes little heed of the warnings.

00:16 : British gliders land around the river Orne and Caen canal bridges, capturing them quickly. They are essential to the coming operations, and are expected to be destroyed by the Nazis if the attack is too slow. "Ham and Jam" is broadcast back to HQ, indicating success.

Meanwhile, in London, SOE typist Elizabeth Small delivers one of the first messages to agents in France that the invasion is starting.

00:17 : some of the first contact between Allied and German soldiers occurs when Oliver Boland crash lands his glider over a trench. The German soldiers surrender immediately.

Private Helmut Romer witnesses a sentry being shot after firing a warning flare; likely the first casualty of D-Day.

00:20 - British and American paratroop landings start. The crucial town of Sainte-Mère-Église is on fire and the flames light up the night sky, revealing the paratroopers to the German troops. The air currents created by the flames mean some are sucked towards the fire. The landings are unhelpfully dispersed.

00:21 : Major John Howard (pictured) and his men capture Pegasus Bridge.

00:30 : Oberleutnant Brandenburger calls his regimental command post that he is witnessing an airborne operation. The scale of this is not yet apparent.

01:00 : Kriegsmarine radars begin to notice the invasion armada which has assembled off the coast. It is, in fact, the largest armada of its kind in history; though nobody comprehends this yet.

Lieutenant Commander Heinrich Hoffmann is informed whilst he is in the cabin of his E-boat. One of the most respected E-boat commanders, he convenes a meeting as he is convinced this is the invasion. He is nervous; his wife asked him several hours earlier "Heinrich, I’m restless tonight. Is there anything afoot?’"
