there are many names for it but its the same thing:
Hartmann was downed for the fifth time, having been rammed by an LaGG-3. Following this incident, he suffered a nervous breakdown and was sent back to Germany on convalescent leave.

edit:
On 25 May 1943, when Hartmann was downed for the fifth time - this time when he was rammed by or collided with a LaGG-3 - he suffered a nervous breakdown, and was sent back to Germany to rest. Back home his father told him that he was convinced that Germany had no chance to win the war. Hartmann returned to the Eastern Front in June 1943 determined to prove that his father was wrong.
