Final answer:
Continuous battles, unfavorable weather conditions, loss of communication with home, and disease outbreaks further demoralized the remaining Germans during the war.
Step-by-step explanation:
The further demoralization of the remaining Germans during the war was caused by a combination of factors. Continuous battles, unfavorable weather conditions, loss of communication with home, and disease outbreaks all contributed to their declining morale.
The German army faced challenges such as supply shortages, including a lack of clean water, which led to the spread of dysentery and cholera among the troops. The arrival of the Russian winter further worsened conditions, with freezing temperatures causing bread rations to freeze and vehicles to break down.
All these factors, from the challenges on the battlefield to the difficult living conditions, took a toll on the morale of the remaining Germans.
