Today, several religious denominations in the USA commemorate the day as "Four Chaplains Day"

Indeed, the US Senate proclaimed February 3, 1998 as Four Chaplains Day, and it is celebrated in the liturgy of the US Episcopal Church as a feast day. But what's the deal?

Well, the four chaplains have names, which I will come to. On 23 January 1943, an American passenger ship, the SS Dorchester, left New York, in Convoy SG19, escorted by three US Coast Guard cutters. Bound for Greenland.

There were about 900 passengers and crew, including approx 750 US Army soldiers.

On 3 February (this was a very slow convoy), the SS Dorchester was torpedoed by German U-boat U-223
