Behind the History

The science fiction in Projekt Kronos is invented. The history around it is not. Every real date, unit, place, person and weapon in the book was checked before it went into the manuscript, and no historical outcome was changed. This page shows the sources, and marks exactly where the fiction steps in.

    “Artificial moonlight”

    Manteuffel’s 5th Panzer Army bounced searchlights off the low clouds to light the way for its infantry. That places Stalker in the center of the offensive, aimed at St. Vith and Bastogne.

    A thin, green line

    The 106th Infantry Division had taken over its stretch of front only days before the attack. The 4th and 28th Infantry Divisions had been sent to this quiet sector to recover from the Hürtgen Forest. Two regiments of the 106th, the 422nd and 423rd, surrendered on the Schnee Eifel on December 19.

    American voices on the radio

    The infantry’s SCR-300 backpack radio worked on FM between 40 and 48 MHz, inside the PRC-158’s band, so Webb could hear 1944 traffic. On the first morning, units reported artillery on every position. The book paraphrases this and does not quote real messages.

    Horses, bicycles and half-tracks

    Volksgrenadier divisions moved their guns and supplies with horses; trucks and half-tracks mostly went to the panzer and SS divisions. By late 1944 each had a fusilier company for reconnaissance, issued a large number of bicycles. The Sd.Kfz. 251 half-track ran a six-cylinder Maybach gasoline engine.

    No Waffen-SS here

    On December 16 the Waffen-SS panzer divisions were with the 6th Panzer Army in the north. The 5th Panzer Army’s sector held army and Volksgrenadier units.

    “NUTS!”

    On December 22, German envoys came through F Company, 327th Glider Infantry, with a surrender demand. McAuliffe’s first reaction was “Aw, nuts.” His G-3, Lt. Col. Harry Kinnard, suggested making it the reply, and Col. Bud Harper delivered it.

    The M16 and its powder

    Designed around stick powder, the rifle fouled and failed to extract when the Army switched to ball powder around 1964. Congress investigated in 1967. The M16A1 added a forward assist, and chrome-plated chambers followed.
