Just as an outline of what I'll be writing about, Saul (might change his name to Gideon or something else) will arrive in Tel Aviv or Jerusalem with a passport and meet a Yishuv rep taking him and some others through when an Irgun member warns the Haganah/Yishuv type bringing in the truck to the kibbutzes that something is about to happen.

Then, of course, bombing. It was fairly common for the Irgun and Lehi to attack the Brits at the time, but to avoid allowing Jewish collateral damage in the process. Sort of a 'welcome to Palestine' post.

Your character's arrival would be different -- she probably came through a refugee camp (earlier?) and was landed illegally, which meant having to avoid the British patrols in the countryside as she is guided in by experienced native Jews (sabras) that are possibly part of the Palmach or Haganah. That's how the majority of Jews emigrated to Israel if they didn't have valid British passports; they were smuggled out of refugee camps in Europe on boats and landed ashore after playing a cat and mouse game of evasion with the Royal Navy, then they had to sort of get smuggled off the beach and into Jewish settlements. Forgery was often involved. A ZOB veteran probably finds all this very familiar.
