I've been thinking about the Easter Rebellion and how only like 1800 men were able to hold onto some significant key landmarks of Dublin and only after the Brtish started just shelling the area were they finally displaced. The Brts even just sent wave after wave of soldiers into the hardened positions losing hundreds of people for like 2 kills. You had the heart of the empire literally next door and though they brought down hellfire on the rebels, it was a pivotal moment that inspired more people to try more in the future and also led to the formation of the IRA from the disparate groups that rose up.
