Ironic that you criticize historians for bringing up inconvenient truths when you bring up all falsehoods:
1) The distance from Egypt to Canaan is ~250 miles. No human could walk that in 2 days. Yes, Exodus is not historical, but your take on it is even falser.
2) We have detailed records of the Continental Army. Almost all soldiers were small farmers, laborers, and tradesmen.
3) The colonists were deeply engaged. Although 20-30% were neutral or loyalist (some sources suggest 1/3 loyalist, 1/3 neutral, 1/3 patriot), there were widespread boycotts, riots, and local militias, especially in New England, and the war was hotly debated.
4) Volunteers turned out in huge numbers. Early battles such as Lexington, Concord, and Bunker Hill were fought almost entirely by volunteer militias who were almost completely unpaid, or only symbolically paid. As the war dragged on, recruitment waned and pay became more consistent but there were never any drafts until 1777.
5) The volunteer army was sometimes ineffective (such as at Camden), but they were effective from the start at guerilla warfare, and later in the war, especially Valley Forge, they became a highly effective force in formal engagements, winning victories such as Saratoga and Yorktown.
6) The Continental Army never employed paid mercenaries, only irregularly paid volunteers fighting for their ideological beliefs. Only the British side employed mercenaries, such as the Hessians.
Overall, you have no business talking about truth one way or the other given how completely you avoided it right now.
