Dachau
There were 5000 priests in Dachau concentration camp near Munich in Germany, 3000 of them were killed in the most brutal ways imaginable. Some were human horses. They were used to drag wagons down to the nearest railway station. When there they contrived to make some of the wheels falls off the wagon outside the home of the local parish priest. In the commotion the priest came out and they were able to whisper to him in Latin that they were priests and needed bread and wine to say Mass.
On subsequent trips the priest would smuggle some bread or sometimes a grape. Late at night, after curfew, and under penalty of instant death, those priests would gather with small groups of the faithful to celebrate Mass and to receive Holy Communion.
One of the survivors described the atmosphere at those Masses.
He said “we got so much out of the Mass”. It was Christ coming to them in their Calvary. They got so much out of the Mass because they brought so much to the Mass.
Bring your sacrifices to the altar…
