Latin conditional clauses - Wikipedia
https://en.wikipedia.org/wiki/Latin_conditional_clausesSubordinate clauses in indirect speech usually use the subjunctive mood. However, if the introductory verb is 1st or 2nd person, the indicative is sometimes retained in a conditional clause, as in the following example: spērō, sī absolūtus erit, coniūnctiōrem illum nōbīs fore in ratiōne petītiōnis (Cicero) 'I hope that if (Catiline) is acquitted, he will work more closely with me in my election campaign'
The Imperfect Subjunctive

In English, the helping verbs might and would are used to express the imperfect subjunctive. In Latin, the imperfect subjunctive is almost always used in a subordinate clause; there is no hortatory subjunctive which uses the imperfect tense.
