Final answer:
The British attack at the Battle of Bunker Hill included a larger number of troops, and involved both naval bombardment and organized military assault on fortified positions, unlike the surprise engagements and quick skirmishes that marked the earlier Battles of Lexington and Concord.
Step-by-step explanation:
The British attack at the Battle of Bunker Hill was significantly different from their attack at the Battles of Lexington and Concord in several ways. Initially, Major General Sir William Howe commanded the British force of 1,500 troops and later reinforced to a total of 3,000 men. The attack on the Battle of Bunker Hill involved a direct and organized military engagement with the Americans using fortified positions on hills, whereas the Battles of Lexington and Concord involved British troops transported by barges and were surprised to find the militias already assembled and alerted.
During the Battle of Bunker Hill, the British Navy in the harbor began bombardment, followed by multiple ground assaults on the American positions. The British faced significant casualties due to the American's strategic fortified defense. Meanwhile, at the Battles of Lexington and Concord, there was no such naval engagement, and the British were on a mission to catch Colonial militias unaware, resulting in the battles happening more as sporadic skirmishes.
In summary, the assaults at Bunker Hill were more structured, involved a larger British force attacking from both sea and land, and were part of a plan to control strategic points overlooking Boston. In contrast, the Lexington and Concord attacks were characterized by surprise, swift movements, and a smaller number of troops engaged in unexpected skirmishes.
