Section IV : On the rights and duties of the belligerent with regard to enemy property - Art. 44.
Art. 44. Hospital ships and sick-wards of vessels are no longer entitled to protection if they are employed for the purpose of injuring the enemy. The fact that the staff of the said ships and sick-wards is armed for maintaining order and for defending the sick and wounded, and the presence of wireless telegraphy apparatus on board, are not sufficient reasons for withdrawing protection.
