John of Luxembourg's Invasion of Lesser Poland
In February 1331, Czech forces under the command of John of Luxembourg launched an invasion of Lesser Poland. The 20,000-strong Czech army attempted to capture Kraków, but the 3,000-strong garrison under the command of Władysław the Elbow-high successfully defended the city. The invasion ended in failure for the invaders but caused significant damage to the region.
