ORIGINAL: wpurdom How does the game model use of Russian RRs in the first 3 weeks of the campaign, when the destruction of RRs was minimal? The first Russian train got through to Minsk on 7/3/1941 (see e.g., https://www.hgwdavie.com/blog/2018/3/9/the-influence-of-railways-on-military-operations-in-the-russo-german-war-19411945 ) and Riga was comparable. Pre war planning ( wargames) gave how many Divs they needed to create.https://history.army.mil/html/books/104 ... 104-21.pdf https://apps.dtic.mil/dtic/tr/fulltext/u2/a279709.pdf https://www.ibiblio.org/hyperwar/Germany/HB/HB-6.html https://shron1.chtyvo.org.ua/David_Stahel/Kiev_1941_Hitlers_battle_for_supremacy_in_the_East__en.pdf Pre war logistical planning showed that after 20 days logistical effort, to support an operational bound of 300 miles in which Russian forced were to be destroyed and the war won) supplies would drop to 10-20% of requirments and an operational pause would result, so as to build up supplies for any further offensives. Maths shows an average of 70 tons per day per formation was all that could be delivered. If priority was given to the Panzer forces, then 33 formations daily requirements could be meet, leaving nothing for any other formations. To go beyond the 300 operational bound ment resupply from the RR, first bound ended at Smolensk, RR conversion to German gauge took till August to convert, so 30 days after getting there, the logistical ability to go on from there became present. The logistics branch of the OKH was blunt in its prediction for another advance from Smolensk to Moscow: ( supply branch of the OKH warned Brauchitsch, Halder and Bock) 'if the intensity of fighting and the operational rythm was to be similar to that of the summer campaign, the supply system would be able to cover a bit over 50% of AGC's needs for a space of time of two weeks. More than that, and the system would collapse and the it would be able to deliver just between 10-20% of the total load of supplies needed'. The 1941 munition supplies reaching the front by month.Source:Germany and WWII Tome June :23077 tons July :101594 August:118855 September: 107870 October:90563 November:68035 Which yields per Div per day.

Total weight 677297200 lbs, is 338648 tons. Time frame 192 days, 1763.8 tons a day expended. Number of Div 146. 12 tons per day per Div. https://archive.org/stream/HalderWarJournal/Halder%20War%20Journal_djvu.txt From Halder diary we find the following: Germany in the East required 32,000 tonnes a day, thats 24 train loads a day each AG.This represented only fuel, ammunition, and limited food/fodder, making no allowance for replacement men, horses, or equipment. POL to munition was a 2:1 ratio. Halder diary, page 203 6th July AGC requires 21 trains a day. Page 242 Wagner gaurentes 14 @6300 tons. Page 246 what that translates into combat loads. "To meet all supply requirements we have available: As of 18 July, 14 trains; 22 trains are necessary to catch up with the three Armies into the areas newly occupied". Ie between 6th and 18th July 14*12=168 promised, 146 deliverd. So 6th AGC requires 21*12 days. QM promises 14 a day, 14*12=168 QM delivers 146/12= 12 a day, =146. 32,000/24 =1333 AGC 21*12 =252*1333=335916 tons. QM promises 168*1333=223944 tons QM delivers=146*1333= 194618 tons. AGC requires 335916 QM delivers 194618 58% of requirement met. Pre war ,logistical planning and actual outcomes were pretty close.
