I'm not sure but I think this is what it means:
When [we] ran in, [we] saw the squadron waiting. This means they ran in wherever they were running in and saw a group of military soldiers that were lined up in a military formation, called a squadron. They saw their friends waiting for them, troubled, looking out at the sea. They beached, or laid the ship (her) ashore and grounded her/the ship to shallow water in the sand. Then they got of the ship and waded through the water onto the sandy beach.
I hope I helped! Again I'm not sure if I am correct but I hope I helped you somewhat.

After the word freeze there shouldn't be any coma.
"cant" is spelled can't so make sure to put an apostrophe.
"its" should have an apostrophe.
"my self" is supposed to be written as myself but if it's a quote coming directly from the text it is ok.
