Why would Pharaoh's army rush into the water? Possible explanation in Song of Songs?

In Exodus 14:23: > The Egyptians pursued them, and all Pharaoh's horses and chariots and > horsemen followed them into the sea. My Question: Why would the skillful, tactical, Pharaoh's army rush into the water? Why would an experienced cavalry commander, upon reaching the seashore, order a charge? My findings: Exo 14 by Lee I listened to Lee's sermon about this, and he talked about how a Rabbi would explain this. Song of Songs 1:9, the groom's first words of praise for his bride are: "I have compared you, O my love, to a company of horses in Pharaoh's chariots" The original word for "horse" is "female horse." A war horse must be a male horse, not a female horse. This beloved is a female. The metaphor is, "I gave you to Pharaoh as a horse harnessed to his chariots." It is a female horse that suddenly appeared in the midst of Pharaoh's chariots. So why did a female horse appear? The lover's words to his beloved are not like horses harnessed to his chariots. Rather, they are like a female horse that suddenly appeared in the midst of Pharaoh's chariots. The rabbi asked, "Why does the Song of Songs record this? When will the beloved (Israel, God's bride) appear before Pharaoh's cavalry?" That is, at the Red Sea. God's miracle was to make Pharaoh's cavalry think Israel was a female horse, and no matter how he commanded, they could not stop. Human commands could not cause an army to charge into the sea. But the horses rushed at that moment. Is this explanation valid? I am new here please notify if this lacks clarity
