this is more and more like my literature classes every day, I swear
Holy, MT wants to write a novel and he wants me to make a novel about it
10 Men to a platoon, 100 men to a Century, 1000 men to a cohort, 10000 men to a Division. If one man deserts, all 10 of his squad are executed, if one man breaks a rule and must be whipped, all 10 of his squad will be whipped.
Increase training discpline, have the troops now train with 4 TIMES the weighted equipment. I want strict military regimens and training routines, soldiers are to undergo extended periods of physical exertion while being deprived of food. Organize the army into a system of 10's.
Tap into my nations strongest economic capability, and begin training a large army of 100000 troops. Gradually of course.
I know this is a pretty f*cked up option, but expel all civilians from the city, send them into the no man's land or perhaps East into the highlands. Hopefully it helps the food problem.
Meanwhile, cancel my naval movements in the north. Instead begin improving the ships. Have iron plating be layered over the inner hull to resist projectiles, equip the vessels with ballistas, catapults, and various other light artillery armaments. Also, have the crews use ballistas equipped with arrows that are attached to coiled rope, this will be used to pull down enemy masts and rigging to cripple their ships. Begin building 40 more ships in the north.
Alright, begin digging a tunnel beneath the city that leads to the enemy's wooden wall, if my engineers can, target the most well defended section of the enemy wall.
By rubber plants, do you mean synthetic rubber? (impossible for you) or try to find natural rubber in your forests? A limestone quarry has been built and is producing limestone. Magnesium on the other hand is found only in small quantities what render the production of guns quite useless.
In any case, your people don't know how to heat up iron hot enough to get rid of all the impurities nor can they get rid of them in any other way due to the lack on knowledge and most likely resources thus steel mills are almost impossible to make. Steam engines are also quite impossible to make due to the lack of materials capable of withstanding the stress what comes with steam engines.
