1823年的一个夜晚,一支法国军队正准备偷袭阿尔及利亚的一个后方要塞。突然,前方不远的沙漠中出现了一群鸵鸟,快速地向他们这边奔跑过来。快靠近时,鸵鸟又摇身一变,变成了阿军士兵骑着面目狰狞的怪兽向法军冲来。法军慌忙开枪开炮予以还击。约十几分钟后,“怪兽骑兵”又莫名其妙地消失了。这些法军怎么也弄不明白,那些“怪兽骑兵”到底是些什么东西?它们的出现为什么和消失一样突然? On a night in 1823, a French army was preparing to attack a rear fortress in Algeria. Suddenly, a group of ostriches appeared in the desert not far ahead and quickly ran over to them. As they approached, the ostrich changed again and became an A soldier who rushed to the French army on the face of a monster. The French hurriedly opened fire and shot back to return fire. About ten minutes later, the “monster cavalry” disappeared inexplicably. How could these French troops fail to understand, what exactly were the “monster cavalry” and why did they appear as suddenly as they disappeared?
