Final answer:
The Continental Army remained resilient due to their determination for independence, unity, and external support from allies. Despite challenges like equipment shortages and variation in training, their shared purpose and strategic adaptations contributed to their perseverance and eventual victory.
Step-by-step explanation:
The Continental Army continued to fight in a seemingly impossible situation for several reasons. A deep-rooted determination and belief in the cause of independence drove them to persevere against all odds. This was a deeply personal war for many soldiers who fought for the freedoms they believed in.
Moreover, there was a sense of colonial unity and shared purpose despite the challenges, such as the lack of manpower, organizational difficulties, variations in discipline and training, equipment shortages, and a lack of uniformity among the troops.
Additionally, external support from allies, like France, played a crucial role in sustaining the Continental Army, by providing much-needed supplies, funding, and military assistance. This lifeline was essential for the army's survival and eventual success. Washington's leadership and the soldiers' courage to adapt to tactics such as guerilla warfare, also helped to even the odds.
Ultimately, these factors combined to keep the army fighting despite the difficult circumstances they faced, culminating in the historic victory for American independence.
