Learning about the Kilmichael Ambush

I have just read about the 1920 KILMICHAEL AMBUSH (LUIOCHÁN CHILL MHICHIL) in "THE WAR FOR IRELAND: 1913-1923," edited by Peter Cottrell.
Carried out by the IRISH REPUBLICAN ARMY, the ambush killed 17 members of the ROYAL IRISH CONSTABULARY (RIC) AUXILIARY DIVISION. The ambush played a significant role in the Irish War of Independence.
I have really enjoyed reading this book, for two reasons:
1. It has taken my mind off my abysmal NCAA TOURNAMENT BRACKET (I am in dead last in the Telegraph Herald pool -- out of more than 160 participants).
2. More importantly, it has shed light on a historical period barely touched upon (if at all) in American school texts.
Tom Barry commanded the IRA's 3rd West Cork Brigade Flying Column and led the ambush at Kilmichael. Did you know he learned his soldiering in the British Army? While serving in Iraq, of all places?
Those are the types of things I have been learning from this book.
The ambush marked a turning point in the IRA's guerrilla campaign.
British reprisals increased in frequency and ferocity following the ambush, which caused more Irish residents to flock to the Republican side. Britain's hold over Ireland was nearing its end.
