The enemy advanced and fired very hotly on the fort, and meeting with a warm reception, there was a very smart firing on both sides. After a considerable time, finding our ammunition was almost spent (gone), I commanded a cessation1 till the enemy advanced within thirty yards, when we gave them such a hot fire that they were obliged2 to retire3 nearly one hundred and fifty yards before they could rally and come up again to the attack. Our ammunition being nearly exhausted4, could keep up only a scattering fire. The enemy, being numerous, surrounded our little fort, began to mount5 our lines and enter the fort with their bayonets. We was obliged to retreat through them, while they kept up as hot a fire as it was possible for them to make. We, having very few bayonets (knives attached to the end of a soldier’s rifle), could make no resistance.” Based on Source 5, what does General Prescott’s letter prove about the battle at bunker hill?
