Career
In May 1940 Major Landzaat was commander of the 1st Battalion, 8th Regiment Infantry (I-8 Rhode Island). On 13 May, his command post, located in a pavilion where a restaurant was located, south of "Ouwehands Dierenpark", was surrounded and attacked. Earlier, on May 12, he had given the command stand firm behind the rubble to his troops.
He organized the defense of his own command post and operated the machine gun.
When the last ammunition was gone, he thanked his troops for their commitment with the words You have fought like heroes, thank you and gave them permission to leave the post. He himself stayed behind until the last moment to preserve.
After the battle, his remains were recovered from the ruined and burnt pavilion and buried in the Military War Cemetery Grebbeberg.
