Although Hitler presented no evidence of a plot by Röhm to overthrow the regime, he nevertheless denounced the leadership of the SA.[40] Arriving back at party headquarters in Munich, Hitler addressed the assembled crowd. Consumed with rage, Hitler denounced “the worst treachery in world history”. Hitler told the crowd that “undisciplined and disobedient characters and asocial or diseased elements” would be annihilated.
In 1847, a group of Irish volunteers, including U.S. Army deserters, joined the Mexican side in the Mexican–American War. These soldiers, known as Los San Patricios or Saint Patrick’s Battalion, flew as their standard a green flag with a harp and the motto Erin Go Bragh.[6][7] Similar flag designs have been used at different times to express Irish nationalism.[8]
