17 July - The Holy Carmelite Martyrs of Compiegne
Their feast day is today in the Carmelite calendar. The best source for their story is William Bush's "To Quell the Terror". You can find it here. (Note that it's half price until September; it's well-worth your $8.48)
If you haven't got the eight and a half bucks, try here for an introduction.
A collect for the feast of the Holy Martyrs:
Deus, qui ob invictam in tuo amore constantiam beatam Teresiam et socias eius de vertice Carmeli ad martyrii coronam vocasti: tribue quæsumus, ut, te fideliter diligentes, ad contemplandam speciem tuæ celsitudinis perducamur. Per Dominum nostrum. Amen.
