John P. "Old Luke" Lucas (January 14, 1890 - December 24, 1949) was a General and the commander of the US VI Corps during World War II.
On January 22, 1944, from the deck of the cruiser USS Biscayne , Lucas oversaw Operation Shingle. Lucas was a graduate of West Point and had served, during World War I, as a battalion commander.
He was replaced by General Lucian Truscott as the commander at Anzio as a result of his perceived unwillingness to fully engage the enemy. This was summarised by Winston Churchill's comment:
- "we hurled a wildcat an the shores of Anzio - all we have is a stranded whale"
