From my understanding yes. It is a basic skill required.
I was reading an article about Steve Fossett and a United pilot flying a 1919 Vimy aircraft across the pond with just a compass, sextant and driftmeter. I just find this fascinating to be able to arrive precisely to your destination after 2000nm or so. Nothing more boring than flying GPS.
I guess this is how the preflight briefing went:
A pilot was sitting in his seat and pulled out a .38 revolver. He placed it on top of the instrument panel, then asked the navigator, "Do you know what I use this for?" The nav replied timidly, "No, what's it for?"
The pilot responded, "I use this on navigators who get me lost!"
The navigator proceeded to pull out a .45 and place it on his chart table.
The pilot asked, "What's that for?"
"To be honest sir," the navigator replied, "I'll know we're lost before you will."
