Why did Halifax become a military anchor during the American Revolution?

During the American Revolution (1775–1783), Halifax became the primary military anchor for the remaining British North American colonies following the establishment of the United States.

Its strategic importance was rooted in its geography; the city is situated on one of the world’s largest and deepest ice-free natural harbours, which made it an ideal location for a British army and navy base. Because the growth of Halifax was historically tied to war and threats of war rather than traditional industries like farming or fishing, the city was already well-positioned to serve as a fortified hub for British military and trade policies in the region.1
