Why did Gage say the loss you have sustained is greater than you can bear after the victory at the battle of bunker hill?

After the victory at the Battle of Bunker Hill, General Gage remarked that the loss sustained by the British forces was greater than they could bear because the battle resulted in significant casualties and highlighted the fierce determination of the colonial forces. Despite technically winning the battle, the British suffered heavy losses, which weakened their morale and military capacity. Gage's statement reflects the recognition that the cost of the victory was far too high and foreshadowed the challenges the British would face in maintaining control over the colonies.
