Eighty-seven years ago today, Germany invaded Poland, an act of aggression that signaled the start of World War II. When I lived in Warsaw in the early ’80s, I’d walk every morning down Opaczewska Street to Grójecka Street to catch a bus or tram. I didn’t know then of the intersection’s significance, but, visiting the old neighborhood a few years ago, I found a monument commemorating the soldiers and brave citizens who gathered there the first week of September 1939 and tried to stop the invading German army. It had been erected after the end of Soviet domination in 1989.
