By May 14, fighting was only occurring in a few isolated areas, including Rotterdam. That same day, at 10:35am, Nazi Germany demanded, in an ill-formatted ultimatum — it was signed simply "the commanding officer of the troops at Rotterdam", without giving the exact identity of the sender — that the Netherlands surrender the city within two hours, to which the commander in chief, General Henri Winkelman, replied through the garrison commander at 12:15 that only a correctly signed ultimatum would be considered. Around 13:30 a new ultimatum was handed out to a Dutch officer, and a reply was expected before 16:30. However, at the same time the bombardment of Rotterdam began, killing about 800 people and destroying large parts of the city, leaving 78,000 homeless. Following the bombardment and German threats of the same for Utrecht, general Winkelman capitulated.
